What are some newer songs to sing for swing choir?

OK, so three of my friends have organized a swing choir at my school. We don't have very many members, probably only like 10-12 right now, and i need some suggestions for some songs we could do. I would like some more modern songs, and something that would be fun, but not too hard to learn. And yes, I have seen Glee, so I would appreciate it if you didn't recommend that to me. Thanks!|||f
