Rekordbox works with Big Sur. You're acting like buying a hub is literally the end of the world, it's not. My interface has USB C. You're seriously grasping at straws with the touch screen argument. Unless you're on a DDJ-200 you can access all the required features from a controller, and let's not forget there are touchpads on laptops. Personally, I have a 4,000+ song library that fits on the internal storage of... Source: over 2 years ago

No need to use the server, Navidrome allows any client to connect remotely (WAN included) and play music that is hosted on the server.

My work flow is Picard > Lyrics Finder > Foobar for BPM, RealGain and DR > Custom python script to pull genre and mood from Last.FM and spotify> then Advanced Renamer to perform naming clean up of folder names. I lowercase and underscore spaces. Also does files if I happen to need Mp3Tag when Picard doesn't find anything. Once this is done I move files on to may NAS. Source: 6 months ago
