Desert island blips

I just downloaded 10 cherished tracks from the iTunes Store. I won't tell you the titles, but I will tell you the artists. Then, if you're mind-numbingly bored, you can try to guess the former. An appropriate prize for the person who gets 'em all correct...or maybe just the dude or dudette who identifies the most. (One attempt per reader.) In alphabetical order, the singers/bands are: Catherine Britt, The Dandy Warhols, dEUS, Gin Blossoms, GLaDOS and Jonathan Coulton, James, Elton John, The Lemonheads, Steve Perry and Tom Petty. Too hard?
