I like beets, but sometimes you need to clean up the tags. A long time ago I made a curses based tagger where you can clean up tags. I still use it today and imo, It's the best tag editor on the market!

Also have a music organizer that copies the files to various directories based on tags:

Both the beets creator and I actually met and developed the tools about the same time on what.cd... rip.
