Excuse me if this was asked already but searching for it takes forever.
Is there any way you can add a way to fetch tags from http://rateyourmusic.com/ ?
Rate Your Music is a database, just like musicbrainz. Sometimes a better one (for the more obscure albums). ALWAYS better for genre tags.
I was also going to ask for a way to implement google images but I saw pone's useful script (Easier to search for, heh).
That's pretty much all, thanks for your time.
