This week the music world caught a powerful case of Obamamania. Arcade Fire rocked a party for the President's staff, Daft Punk and Will.i.Am tipped their musical hats (or, in Daft Punk's case, robot helmets) to the Commander in Chief. Even Be Your Own Pet's Jemina Pearl and Animal Collective embraced Obama's message of change.
