Recently, the tagging with #abcde doesn't work anymore. It calls #eyeD3 but it doesn't set the tags because of missing quotes in the call. I'm using the "newest" version on fedora which is from 2019.

Any idea how that happens?

So I found out that it's because of the non matching genre. I thought it would be no problem as it wasn't in the past but adding --non-std-genres to the #eyeD3 options helped:.
EYED3OPTS="--non-std-genres"

Added it to my #dotfiles repository with a comment why I chose this setting
