I have an artist listed Foo Fighters.

I also have an artist listed Unknown Artist with Foo Fighters songs.

I type in Foo Fighters to the Unknown Artist (yes, I clicked edit) and when I press Enter it says Unknown Artist again.

I also have a couple songs listed Metallica in the Artist box at the bottom left when you listen to it, but the song is in the file of System of a Down.

Just picture this happening pretending you know these artist, and you're trying to fix it but it doesn't work. So you grab a bat and swing at it as hard as you can. Not to mention having it broken like that for 3 Years.

…it doesn't work.
