Really loving Billionaire by Travie McCoy right now...and Tipsy by Chingy (I think that's right).

Living Fire - Man the Prodigy's Invaders Must Die album is DOPE! That's on my play list as well, although mine is so played out I have to completely redo mine! Pendulum is one of my fav groups too - Holy crap their stuff is on fire. Have you ever checked out High Contrast? *head explodes*

Some of Justin Timberlake's stuff is good for working out too.

You all have some great suggestions :)
