it's interesting to see people name artists that someone else has already listed. either some of you don't pay attention 100% to what you read or you don't bother reading other people's posts to begin with.
For anyone who didn't realize that this picture has been around for a while (I saw it years ago), I just did a google search for "virgin music picture quiz answers" and found sites listing anywhere from 65-75 answers. If you're lazy like me, an answer key never hurts while working on this kind of stuff.
