Thanks for all your work on this.
I have a couple of feature requests. When matching tracks in the library to the Discogs track name would it be possible to ignore parentheses? E.g. I've got a track named "Nappy Head" in my library and the tagger didn't match it to the track "Nappy Head (Theme from "Ghetto Man")" in the Discogs database.
Also, would it be possible to use the "Grouping" tag where appropriate? Like
here, where the tracks are grouped into sonatas. Or, like
here, where the they're grouped into "The Death Side" and "The Life Side".
