How many songs are available on Spotify?

How to get close to this number

Multiply years by upload rate. The explanation gives around a hundred thousand new tracks a day; over a decade and a half of operation that alone accumulates hundreds of millions — except the catalogue also inherited most of recorded music history at launch. Tens to hundreds of millions is the right band.

The unlistened share is the fact that reframes the catalogue: a large portion of tracks have never been played even once. A library that grows faster than humanity can listen to it is a genuinely new condition — for all of recorded music history until now, the constraint was availability rather than attention.

That is the same shape as Steam games, podcasts and online stores elsewhere on this site. Remove the cost of distribution and supply expands without limit while attention stays fixed, so the median item in any zero-cost catalogue reaches nobody. The catalogue size measures how easy uploading became, not how much music people hear.
