upbeat playlist for grading

I'm coming to the conclusion that I need to make myself an upbeat playlist to use while I grade. At the moment, it's tiny, and includes Colbie Caillat's album "All of You" and song "Try", "Say Hey (I Love You)" by Michael Franti & Spearhead, and "Take Me To Church" by Hozier. (all added to my music collection recently)

I'm going to go hunt through my existing collection also, but I was curious if any of you have suggestions for songs you tend to think of as especially upbeat songs?
