I love the song Harder, Better, Faster, Stronger by Daft Punk. In fact I’ve been listening to the thing off and on all day. I just ran across this video featuring the song that I thought was really cool. It starts off a bit cheesy, but hang in there… it’s well worth it.

EDIT:Ok, then I saw this one which is probably even better.
