Scrobbles through Last.fm? But I don't think you can export directly from Spotify (maybe through playlist and one of the music transfer tools? I mostly use Spotify to listen through a recommended album. And ads bother me, so I switched to premium (It's 2.99 for me).

I have a local library of ALAC albums that I like. I used Syncthing to sync it to my home server, where there is a Plex installation (When I want to play via the ATV). And I convert to AAC 256kbps to my iPhone (Bluetooth is lossy anyway). More hassle than playing via Spotify, but the latter's UX is so bad that it's worth it. Also I have some excellent headphones (Hifiman Sundara and Sennheiser 6XX).

While Plex has some shortfalls with handling music (mostly that most tags are applied at the album level, not the track level), it's still the best option I've tried for handling your own streaming setup. The PlexAmp[0] app they developed sands off many of the rougher UX elements from the web app, but it requires a paid version of the Plex server.

When you say "own" what do you mean? CD's? Or some digital purchase?

I believe modern iTunes is DRM free so you can keep all your purchases safe that way. Alternatively Youtube Music allows you to upload all your local music so you can their service to stream it. I've bought things on iTunes and then uploaded them to Youtube Music.

Sorry I should have been more specific. I care less about the actual song content itself than having a synchronized list of the names (i.e. metadata) of all the songs I like/save/listen to.

TIDALs sister company TBD touches on that here https://developer.tbd.website/blog/what-is-web5/

If you have iOS, there's an app called SongShift. I think some features are paid, but I used it once a few years ago to transfer my Spotify library into Apple Music to try it out. It looks like it can also export to JSON too (that might be a paid feature?).

> A decade ago I moved off the good iTunes and foolishly lost my complete library of metadata of songs, so I want to avoid that again.

Relying on anything that is closed source, or worse, an online service, brings with it the eventual inevitability of losing everything. No product or company lasts forever.

For things that are ephemeral in interest (e.g. movies you only care to watch once), that's fine.

For things that you really like and want to have a strong guarantee you can enjoy them later, the only solution is open formats and have the data in your control.

For all the music (and a few handful movies) that I want to be able to enjoy forever, I keep them locally in a redundant backed up ZFS server. No corporate change of heart can ever take those away from me.

I run a homemade script to scrape my profiles on Mixcloud and YouTube for my activity. Hardly a good universal solution I'm afraid.
