There are a lot of reasons for this but mostly because music streaming has been so popular that it wiped out the market for music. Its also a huge pain in the ass to sort and organize music when nobody follows a standard when they rip music so it makes automating things a lot harder as well.

I have several thousand songs I’ve downloaded over the last 25 years but even with modern tools like MusicBrainz Picard or Lidarr, there’s no good way to organize your collection. You wind up with a bunch of singles or oddball songs from a compilation album, from a sampler, or you download an album and half of the songs come from the US version while the other half is from a UK version of the album and the uploader forgot to include a bonus track that comes on that version. Its just a huge mess that you dont see with movies and TV because apart from things like a “Director’s Cut” or “Extended Version,” you know what you’re getting when you download them.

Additionally, playback isnt easy either. Are you going to manually transfer hundreds of files to your phone? Stream from your home media server to your phone and use a bunch of bandwidth? You’re getting tired of 30% of your songs so are you going to go through your collection one by one and erase them?

There’s a huge convenience factor for services like Spotify. With movies and TV the convenience factor definitely favors the self-hosted side of things.
