For as many text-based music players as there are, you’d think someone would take pity on us poor text-only proponents and give us a tool to tag all those audio files.
For more convoluted tagging issues, I fall back on lltag.
It’s difficult for me to explain what lltag does, except that I think it tries to reason out the name, artist and album of audio files, and correctly tag them.
You get the chance to be a hero by helping lltag with the format from the file name. lltag can reverse that process too, and rename files from tags.
Of course, it does more than that. The home page can give you tips and examples.
This, in conjunction with beets and maybe even the renameutils in an emergency, should flesh out your need to manage your audio collection.
