How to Put a Number on Music Quality

A month after release the typical album does 39% of its first week, a year in 11%, ten years in 2.4%. How rare the exceptions are says a lot about quality.

Research, October 29, 2026, 9 min read

A month after release, the typical album is down to 39% of its first week. A year in, 11%. Ten years in, 2.4%.

We tracked 126,342 albums on Spotify every day for nine months. Almost all of them follow that curve. The few that break it, and how rare they are, are the closest thing streaming has to a measure of quality.

The short version

  1. A month after release, the typical album does 39% of its first week's daily streams. A year in, 11%. Ten years in, 2.4%, and by then it has almost stopped falling.
  2. Breaking that rule is rare. A month in, 1 in 26 albums is still at its first-week level. A year in, 1 in 68 doubles its pace over nine months. Ten years in, about 1 in 100.
  3. Launch size doesn't predict who breaks it. Across 241 big 2026 albums, how big an album opened told you almost nothing about how much was left on day 120.
  4. Old albums usually break it because of something outside them: a film, a festival, an anniversary. A moment fades within weeks. A new audience finding the album stays.
  5. Breaking the rule means people choosing an album again when nobody is pushing it. That's replay value, and it's the closest number to quality there is.

1 month, 1 year, 10 years

How much of its first week a typical album still does, and how many albums break the rule at each age.

1 month

39% of its first week's daily streams. Each dot is a 2026 album: its streams on day 30 against its own first week.

  • Kept twice the typical share: 1 in 10
  • Still at its first-week level: 1 in 26

287 albums

1 year

11% of its first week's daily streams, estimated. Each dot is an album about a year old in January: how its streams changed by October.

  • Grew instead of fading: 1 in 4.5
  • Doubled: 1 in 68

409 albums

10 years

2.4% of its first week's daily streams, estimated. Each dot is an album about ten years old in January: how its streams changed by October.

  • Grew instead of fading: 1 in 3.4
  • Doubled: 1 in 100

2,696 albums

The rule is steep at first and then flattens. A month in, the typical album has lost three-fifths of its first week. By a year it's down to about a tenth, and still losing a fifth of what's left each year. By ten years it's at 2.4% and barely moving: the people still playing it are the ones who chose it.

Breaking the rule is rare, and it gets rarer the bigger the break. A month in, 1 in 26 albums is still at its first-week level. Among albums a year old, about 1 in 4.5 grew over the nine months we watched, but only 1 in 68 doubled. At ten years growing is more common, partly because Spotify itself keeps growing, yet doubling stays at about 1 in 100.

The rule, up close

The first six months of every big 2026 launch, and how long each halving takes after that.

Here is the rule in detail. We took every album released in 2026 that opened with at least 3 million streams in its first week (355 of them) and compared every later day with its own first week.

The first six months of 355 albums, each against its own first week

100% is the album's own average day in its first week. Day 1 is the first day Spotify's count moves, usually two days after release.

The first week holds steady. Then the new-music playlists move on and the typical album is down to half by day 21. After that it keeps losing listeners, but more and more slowly: each halving takes longer than the one before, until after about fifteen years it stops falling at all.

How long each halving takes

  • 100% → 50%, 21 days
  • 50% → 25%, 50 days · 2.4× the one before
  • 25% → 12.5%, 7 months · 4.2× the one before
  • 12.5% → 6.3%, 2.4 years · 4.1× the one before
  • 6.3% → 3.1%, 4.6 years · 2.0× the one before

Each bar is how long a typical album takes to lose half of what it has left, drawn to scale. Lighter bars are estimated from older albums.

That slowing is the exceptions showing up in the average. The people who were only there for the launch leave fast. The ones who are left chose the album, and they leave slowly.

Big launches aren't the exceptions

Six 2026 albums: daily streams since release, each line on its own scale.

  • ICEMANDrake · Front-loaded, 64.8M a day, 5.2M a day day 165, 8%
  • The Fall-OffJ. Cole · Front-loaded, 17.3M a day, 1.2M a day day 181, 6.8%
  • ARIRANGBTS · Superstar launch, 69.9M a day, 11.9M a day day 200, 17%
  • you seem pretty sad for a girl so in loveOlivia Rodrigo · Typical curve, 57.4M a day, 17.3M a day day 137, 30%
  • The RomanticBruno Mars · Holds its pace, 21.2M a day, 4.8M a day day 200, 23%
  • VisitorSIENNA SPIRO · Slow burn, 3.9M a day, 7.5M a day day 117, 192%

If launch size measured quality, the biggest launches would hold up best. Drake's ICEMAN opened at 65 million streams a day, the second-biggest launch of the year. By day 165 it was down to 8% of that. BTS opened even bigger and kept twice as much. Sienna Spiro's Visitor opened at a sixteenth of Drake's size and was doing almost twice its own first week three months later, as people found its songs on their own.

Is that the rule? We checked all 241 big launches of 2026.

Does a bigger launch hold up better?

Each dot is one 2026 album. Across: how big it opened, in streams a day. Up: how much of that it still did on day 120. The dashed line follows the middle.

No. If size predicted staying power, the dots would slope. They're a cloud. The biggest launches start with a sharper first day and fall harder in the first month, then catch up. By day 120, albums of every size keep between 16% and 27% of their opening.

A launch measures how many people were told about an album. Marketing, playlist slots and a loyal fanbase all show up here. What it can't tell you is whether people will want to hear it again, and that's the part that looks like quality.

How an old album breaks the rule

Six albums that came back in 2026: daily streams, a week's average. The dotted level is each album's January pace.

  • Thriller Michael Jackson · 1982, ×6 at the peak, against January, 2.0× now, against January, Michael opens Apr 24 January level Feb Apr Jun Aug Oct, New listeners stayed: still above January
  • DeBÍ TiRAR MáS FOToS Bad Bunny · 2025, ×4 at the peak, against January, −42% now, against January, Super Bowl Feb 8 January level Feb Apr Jun Aug Oct, Back on its usual decline
  • Best Of Hannah Montana Hannah Montana · 2011, ×7 at the peak, against January, −11% now, against January, Anniversary special Mar 24 January level Feb Apr Jun Aug Oct, Back on its usual decline
  • Go The Chemical Brothers · 2015, ×35 at the peak, against January, 11.3× now, against January, Apex on Netflix January level Feb Apr Jun Aug Oct, New listeners stayed: still above January
  • My World Justin Bieber · 2009, ×8 at the peak, against January, 1.6× now, against January, Coachella Apr 11 January level Feb Apr Jun Aug Oct, New listeners stayed: still above January
  • Halloween Howls: Fun & Scary Music Andrew Gold · 1996, ×27 at the peak, against January, 23.7× now, against January, October January level Feb Apr Jun Aug Oct, Comes back every year

Old albums come back all the time, and something outside the music always starts it. What happens after is the useful part. Look at where each line ends.

A moment borrows attention. Bad Bunny's Super Bowl halftime show took DeBÍ TiRAR MáS FOToS from 17 million streams a day to 64 million. By October it was 42% below where it started the year. Millions of people pressed play once, for the occasion, and went back to what they were listening to before.

A discovery brings in people who stay. The Michael biopic took Thriller from 3.5 million streams a day to 19 million, and six months later it still runs at twice its January level. A Netflix film put The Chemical Brothers' Go in front of a new audience, and it's still at 11 times its January level. Some of the people who heard these for the first time liked them enough to keep playing them.

That's replay value working as a test. A spike is attention, and attention can be bought or scheduled. What's left after the spike is choice: the new listeners who decided the album was worth hearing again.

What kind of album lasts

Each album scored against albums of the same age. 100 is a typical album its age; 110 means it held on to 10% more of its audience.

By genre

  • Latin 1,473 albums, 110
  • Country 641 albums, 106
  • Rock 763 albums, 106
  • Metal 200 albums, 102
  • Hip Hop 3,659 albums, 100
  • R&B 491 albums, 99
  • Pop 3,429 albums, 98
  • Alternative 2,252 albums, 97
  • Dance 684 albums, 96
  • Folk 334 albums, 95
  • Electronic 623 albums, 95
  • Classical 311 albums, 90
  • Jazz 174 albums, 82

By kind of record

  • Greatest hits 3,541 albums, 108
  • Deluxe or anniversary 2,459 albums, 103
  • Live album 1,404 albums, 102
  • Soundtrack 686 albums, 100
  • EP 2,883 albums, 100
  • Single 16,026 albums, 99
  • Studio album 16,123 albums, 99

Latin albums hold on to their listeners best, followed by country and rock. Jazz and classical lose theirs fastest, probably because a lot of what Spotify files under them is background music on mood playlists, and those playlists rotate. Greatest-hits albums hold up best of all: they're made of songs people already chose. And the bigger an album already is, the better it holds. On streaming, popularity compounds.

This covers albums from two to fifteen years old with at least 50 million streams.

From exceptions to a number for quality

So far this has been about how albums age. Here's why the exceptions matter. Ask ten people whether an album is good and you get ten answers. Critics disagree, awards follow fashion, and the numbers everyone quotes (first-week sales, debut chart position, launch-day streams) mostly measure how much was spent telling people the album exists.

A number that tracks quality would need to pass three tests.

  1. It covers every album: Not just the ones critics review or awards notice.
  2. It's hard to buy: Marketing can buy a first week. It can't buy year three.
  3. It gets more reliable with time: Hype wears off. What's left is people choosing the album.

Replay value passes all three. Long after the marketing stops and the new-music playlists move on, people either keep pressing play or they don't. Spotify counts every one of those plays, for every album, every day, and we record those counts.

Here's the measure we use. Take an album's average day over its whole life so far, and compare it with an average day now. An album at 200% is being played twice as much today as it was on an average day of its life, including the launch. One at 20% has lost four-fifths of its audience.

Replay value, on two albums

  • Don't Forget About Me, Demos Dominic Fike: Average day since release 1.2M, A day now 3M. Replay value 239%
  • Coloring Book Chance the Rapper: Average day since release 655K, A day now 164K. Replay value 25%

Daily streams. Both albums have more than a billion streams in all.

One correction matters. Spotify has grown a lot since 2014, which flatters older albums: the typical billion-stream album from 2014 runs at 153% of its lifetime average today, and the typical one from 2021 at 57%. So every album is ranked only against albums released the same year.

Replay value, measured

Billion-stream albums from 2014 to 2021: today's daily streams against the album's own average day since release, ranked within each release year.

Most replayed: furthest above their lifetime average

  1. Don't Forget About Me, Demos Dominic Fike · 2018, 239 % 3M a day
  2. Me llamo Raquel Banda Machos · 2018, 228 % 743K a day
  3. No Vacancy Treaty Oak Revival · 2021, 220 % 1.3M a day
  4. Cinta Luar Biasa Andmesh · 2019, 201 % 802K a day
  5. songs Adrianne Lenker · 2020, 187 % 1.3M a day
  6. Euphories Videoclub · 2021, 185 % 906K a day
  7. Here Comes The Cowboy Mac DeMarco · 2019, 184 % 939K a day
  8. FOR THE HUMANS WHO TAKE LONG WALKS IN THE FOREST AURORA · 2021, 155 % 1.4M a day

Least replayed: furthest below it

  1. BREATHE felix jaehn · 2021, 13 % 125K a day
  2. Lil Pump Lil Pump · 2017, 17 % 82.9K a day
  3. I Decided. Big Sean · 2017, 20 % 99K a day
  4. Bobby Tarantino II Logic · 2018, 20 % 102K a day
  5. Coloring Book Chance the Rapper · 2016, 25 % 164K a day
  6. Good For You Aminé · 2017, 27 % 122K a day
  7. Pretty Girls Like Trap Music 2 Chainz · 2017, 28 % 105K a day
  8. Professional Rapper Lil Dicky · 2015, 31 % 87.6K a day

The most replayed albums are mostly slow builders: Adrianne Lenker, Mac DeMarco, Videoclub, AURORA, the Texas country band Treaty Oak Revival, a set of Dominic Fike demos. Few of them were big launches. People found them over years and kept them.

The least replayed are mostly rap albums from 2015 to 2018 that were huge when they came out. Chance the Rapper's Coloring Book won the Grammy for Best Rap Album. It now streams at 25% of its lifetime average. Lil Pump is at 17%.

That's the first sign the number is measuring something real and not just popularity: it disagrees with the charts and the awards, in a direction you can explain.

Where replay value gets it wrong

Replay value isn't quality itself, and it fails in ways worth knowing:

Background music
Sleep sounds, study playlists and mood jazz replay forever because nobody is really listening. That's replay without choice. Comparing an album with others of its kind helps.
Moments
Some great records belong to one summer, one scene or one sound. Coloring Book faded, and it's still a great album. Replay value can't see an album that mattered intensely for a while.
Hard listens
Difficult, long or harrowing albums can be masterpieces that people play once. Replay value rewards music that fits into daily life.
The machine
Spotify's recommendations feed replays back into more replays, and its own growth lifts old albums. Ranking each album against others of the same age and year removes some of that, not all.

A launch measures how many people were told. Replay value measures how many people cared.

Even with those holes, nothing else comes as close. It costs nothing to collect, it covers every album on the largest music service, it can't be bought the way a launch can, and it gets harder to fool the longer you wait. If you want one number for whether an album is good, the best one available is whether people are still choosing it years later.

For artists and labels, that changes what to look at. The first three weeks are half the story of a launch, but they aren't the asset. The asset is the tail, and the tail depends on whether people come back on their own once the playlists move on.

How we measured this

Counts
StreamClout records Spotify's public play count for every track of more than 400,000 artists each day. An album's daily streams are the day's increase in its tracks' counts. Spotify shares one count between versions of a recording, so a song on an album and its deluxe edition counts toward both.
Window
January 22 to October 28, 2026: 126,342 albums, every album with 50 million or more lifetime streams plus every 2026 release with 3 million or more.
Launches
355 albums released January 24 to September 30, 2026, made of new recordings, that averaged at least 430,000 streams a day in their first week. Picking by the first week keeps later success out of the selection.
Exceptions
At one month: 287 2026 albums of new recordings with a first week of at least 430,000 streams a day, their median day 27 to 33 against their first week. At one year and ten: original studio albums and EPs with 50 million or more streams, about a year old (409) or about ten years old (2,696) in January, their median day of October 9 to 24 against January 24 to February 8. Albums whose January pace was under a twentieth of their lifetime average were left out: that's an album whose tracks moved between editions, not a real change.
Long run
28,645 studio albums and EPs with 50 million or more streams: median daily streams of January 24 to February 8 against October 9 to 24, by age, chained from day 150. It assumes today's ten-year-old albums aged the way a 2026 release will, and isn't adjusted for Spotify's own growth.
Estimates
No data was collected from August 10 to 29. In the album lines, those days are estimated by a steady rise or fall between the week before the gap and the week after it, and drawn dotted. They only fill in the lines: no figure or score on the page uses them.
Clean-up
Days Spotify didn't update its counts were merged with the next day, and one-day jumps where Spotify merged two counts were left out.
