Good Pop, Hip Hop, and Pop Rock Songs?

I'm looking for some songs that are either pop, pop rock, or hip hop. NO RAP. I am already a huge Ke$ha fan- I know almost all of her songs. I love Katy Perry and Taio Cruz. NO DISNEY STAR SONGS. I would appreciate songs from Far East Movement. I know Like a G6 already. I would also like to be introduced to more artists. Thanx!! :)
