musicbee for library and music management and sync playlists over wifi locally
maybe combine with mp3tag if you don’t like the built in tagger in musicbee. Only reason for me to use mp3tag is to include the style tag from Discogs into the genre field. Not possible with musicbee. If this is not in your interest musicbee’s tagger is amazing.
there are two private trackers focusing on music only. Insane collections. One is very hard to get into. The other is way easier.
