Additionally, I also blame Grease for the sheep-i-ness, because I've been listening to it fairly solidly for the past three days. It's driving me insane; yet I. Can't. Stop. Listening.
Some stats: Yesterday, Grease was at #94 (146 plays), now it's at #41 (271 plays). And that's only for the 9 songs out of 24 on the soundtrack I have the labelled artist as 'Grease'. Six labelled as Sha-Na-Na, and the others the random singers/composers for whichever song.
Name your top 10 most played bands on Last.fm:
01. Belle and Sebastian 
02. Talking Heads 
03. Dar Williams 
04. Rufus Wainwright 
05. The Beatles 
06. Bright Eyes 
07. Death Cab for Cutie 
08. The Libertines 
09. Ryan Adams 
10. Rilo Kiley 
Now answer the questions according to the numbers:
