From Kim F. After seeing Green Day's American Idiot musical (which she thought was awesome), she has been loving their song, 'Holiday', to workout to. She also likes Gotye's, 'Somebody That I Used to Know' though she claims this song is better somewhere in the middle of a run once you are in the zone. Thanks for sharing, Kim!
Listen to this:
Holiday - Green Day
Somebody That I Used To Know - Gotye (feat. Kimbra)
