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. :)
To add to the audio compression: it isn’t possible to further compress an mp3 file without losing any quality. You can either:
If you’re willing to spend some extra time learning about audio compression, you can download lossless files and compress those directly to whatever format and bitrate you want. The quality will be better than option 1 above, as the audio is only lossely compressed once instead of twice.
