I’m using MusicBrainz Picard. However there are some tricks to spare you some nerves:

• you can set weights to release types in the settings. Singles and compilations should have a lesser weight than albums.
• Don’t add too much music at once. Or you’ll get crazy selecting the correct releases. I usually go with one artist a time. Especially for older artists I just add one album a time. You can enable the file Browser in the view settings, than you can just drop them in one after the other.
• in the right pane you can just drag and drop whole releases to merge them together.
• Also noticable is the rename feature in the settings. It’s just awesome!

That’s a cool approach! Reminds me of the old Napster 🤓

Awesome! I just learned something today. Thanks for pointing it out so detailed!

yt-dlp can handle YouTube Music Links. Just tell it with -x --audio-format mp3, that you don’t want the Video, but an mp3 (opus can’t be tagged). I use it to obtail whole artists, then I tag them with MusicBrainz Picard. I’m sure there is a way to automate this. yt-dlp has also a Python library. However I haven’t used it for now.
