What are some songs for prom? (2009)?

I'm on the prom committee and I have to give the DJ a list of songs. A LOT of songs. I need the clic slow songs like, "All My Life" by K-C and Jojo, but also some newer slow songs. And some up-beat hip hop, like Lil Wayne. I need someone's help PLEASE! As many songs as you can possibly think of; there is no limit. Also, they can be any genre; hip hop, country, rock, whatever. Thank you!
