The short answer
You promote an old song the same way you'd promote a new one: get it onto playlists, use Spotify's own catalogue tools (Discovery Mode, Showcase), and give it a real reason for people to play it now. Release date barely matters to Spotify's algorithm, what matters is recent engagement, so a two-year-old track with a fresh spike in streams gets treated like new music. Catalogue now makes up roughly three-quarters of all US streaming, so most listening already happens on old songs, artists just aren't the ones driving it.
Three quarters of everything streamed on Spotify right now is a song people already know. Not new drops, not the single that came out last Friday. Old music, quietly doing the heavy lifting while everyone's attention goes toward whatever's about to come out next.
That number should change how you think about your own catalogue. Every week someone tells us a song is "done" at six months old, sometimes younger. Released, pushed for a few weeks, then left alone while all the energy moves to the next single. Assuming a track stops needing any push just because it isn't new anymore is a cousin of the same lie we've written about before, that good music markets itself. It doesn't, and neither does old music, on its own.
Here's the part nobody says out loud: nobody streams your back catalogue by accident. Not you, not your fans, not Spotify. If a two-year-old song is racking up plays, something specific caused it, a playlist add, a TikTok clip, a sync, an algorithm that decided, based on recent behavior, that this track deserves another look. Streams don't accumulate quietly just because a song exists somewhere on your profile.
The release date is doing less work than you think
Most artists treat their release date like an expiration date. Six months out, the song is "old news," so the pitching stops, the posting stops, any real campaign around it stops. Meanwhile catalogue is eating the chart. Music Business Worldwide reported that catalogue tracks, anything 18 months or older, claimed 75.8% of total US on-demand audio streams in the first half of 2025, based on Luminate's numbers. Current releases, everything younger than that, made up the remaining 24.2%, and that share has been shrinking year over year, not growing.
Read that again. Most of what actually gets streamed in the US isn't new music. It's old music still finding new ears, through playlists, syncs, algorithmic recommendations, and content moments that have nothing to do with when the track came out.
I know what you're thinking: sure, but that's Fleetwood Mac and Kate Bush, not me. Fair, sort of. "Running Up That Hill" peaked at number 30 on the Hot 100 back in 1985. Almost forty years later, a Stranger Things sync sent it into the top ten with zero new material behind it, just an old recording finding a new audience. Glass Animals' "Heat Waves" is the smaller-scale version of the same story: it had been out for well over a year before it hit No. 1, after taking off on TikTok and pulling streaming and radio along behind it, per Billboard's reporting on the trend. Neither of these is a freak accident. They're the predictable result of a system where recent engagement, not release date, decides what gets recommended next.
What actually revives a catalogue track
None of this works if you just wait. Here's what does.
Playlisting still works on old tracks, and it's underused. There's no rule saying independent curators only want brand new music. A well-fitting three-year-old track lands on a mood or genre playlist just as easily as a fresh single, and honestly it's an easier pitch, since you've got real listener data to point to instead of a promise. We've made 12,030 playlist placements since 2019, and a fair number went on catalogue tracks that never got a proper push the first time around. If you're not sure why a pitch keeps getting turned down before you even get to that stage, we broke down the real reasons curators say no here.
Discovery Mode exists for exactly this. It's not a release-day tool. Spotify requires a track to have been live for at least 30 days and clear a streaming threshold before it's even eligible, which tells you who they built it for: songs that already have some life in them, not brand new drops. If you're the type who checks Spotify for Artists constantly hoping for movement, this is one of the few actual levers to pull instead of just refreshing the app.
Showcase does the same job, more directly. Spotify's own page for the tool lists this exact use case: support a tour announcement, highlight a song that's gaining traction, mark a release anniversary, or bring listeners back to a catalogue track that fits a current moment. Spotify built these tools because catalogue drives real revenue for them too, and they'd rather you use them than let a good song sit untouched.
Content moments beat patience every time. A fifteen-second clip, a fan edit, an unexpected mention on a subreddit, a sync placement nobody saw coming. All of these create the exact recent-engagement signal that Spotify's Radio and autoplay reward. The song's age is irrelevant to the algorithm. What it did in the last 28 days is everything.
If you've got a catalogue sitting untouched, don't treat it like a museum exhibit. Go back through it, find the two or three tracks that still hold up, and give them a real push instead of hoping the internet stumbles onto them first. That's basically what we do for a living. A lot of our 2,047 campaigns so far have landed on songs that were already a year or two old by the time the artist came to us. Old doesn't mean dead. It means unpitched. Fix that part and the streams tend to follow.
Common questions
How do I promote an old song on Spotify?
Pitch it to independent playlist curators the same way you'd pitch a new single, since Spotify's own editorial pitching only works pre-release. Turn on Discovery Mode if you're eligible, run a Showcase campaign from Spotify for Artists, and give people an actual reason to play it now, like an anniversary, a sync, or a clip on TikTok or Reels.
Does release date affect Spotify algorithm placement?
Less than most artists think. Spotify's Radio, autoplay, and Discover Weekly run on recent listening signals, saves, and skip rates, not on how long ago a track came out. A song from 2021 with a sudden spike in engagement can get pushed the same way a brand new release does.
Can old songs still go viral on Spotify or TikTok?
Yes, regularly. Kate Bush's 'Running Up That Hill' hit the top ten decades after its original 1985 chart run once a Stranger Things sync gave it a second wave. Glass Animals' 'Heat Waves' did the same on a smaller scale, taking off on TikTok more than a year after release and driving new streaming and radio play off the back of it.
What is Spotify Discovery Mode and can I use it on old tracks?
Discovery Mode is a Spotify for Artists tool that flags tracks for priority placement in personalized recommendations. It's actually built for already-released songs, since a track needs to be live for at least 30 days and clear a streaming threshold before it's even eligible, which makes it more useful for catalogue than for a brand new single.
Is catalogue music really more streamed than new releases?
Yes. Luminate's data, reported by Music Business Worldwide, put catalogue tracks (18 months or older) at 75.8% of total US on-demand audio streams in the first half of 2025, with current releases making up the remaining 24.2%. That share has been growing, not shrinking.
