Do I use a website to download songs off of YouTube or Spotify?
Where should I store the music? I haven't any clue about self-hosting. I'm running GrapheneOS, is it enough to save the songs in Files and play in an app like Auxio? Maybe sync with SyncThing?
What's the best way to compress mp3 files but still retain the quality (even possible)?
Could really use some help as I'm very inexperienced. :)
Oh youre gonna do the big jump, good luck with that😄
PS. If you care about your spotify listening history there is a way to get your listening records in your email (takes about a month tho). And about music discovery there's Innertune (the forked version is better) which uses yt music without an account or Listenbrainz which can help you find songs and artists/bands.
You persisted despite the struggles and you made it, well done!
