I have been having a hard time finding a solution to my problem of sorting music from both Youtube music and Bandcamp. I have tried Picard and while it is good I have had problems with it. For example it has made songs shorter (they now end to soon.). So far the only solution I have found is to use Picard and manually review every song I own, and since I have thousands of songs It would take quite long.

I'm using Jellyfin with Finamp to play my music, and sometimes add lyrics via the Jellyfin app when they are missing.

How have you people solved this or similar issues? Does someone have a automated setup that works well?
