hmmm, motivational music....
Switch- will smith
punjabi wedding song (from Bride and Prejudice, if I could ever find the song!)
Hung Up-Madonna
Don't Funk with my heart - black eyed peas
Gold Digger - Kanye West
AND who can forget the Deft Punk classic, "ONE MORE TIME"
if nothing else, it gets so annoiying you work out faster to make it go quicker.
