Once downloaded, MusicBrainz Picard is going to be your best friend in organizing everything. Then choosing how you host it, I just have it in Jellyfin with my other media.

Soulseek is great, welcome. OT I can’t really believe people suggest ripping music from Youtube as an alternative, how can you listen to such crappy quality music? It’s usually compressed and then when you upload to youtube it’s compressed again, then guess what it’s compressed again when it’s converted to an mp3 because youtube is using different compression. Do yourself and your ears a favor and seek out quality music.
