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.

Remember to have 2 backuo sources to store data

I found slskd’s GUI to be a bit nicer than standard soulseek, and it has plugins for the *arr suite.

That being said, I use it for downloading, then run musicbrainz Picard to mass rename/sort/fix metadata, skipping the music *arr module due to past issues with it.

For accessing my music remotely I use jellyfin.
