Give me a list of awesome songs 4 tweens?

I'm twelve and i can't really put together a list of awesome songs for my new mp3 player. Please, don't list some old 1960 songs or country crap like that. I live in the Atlanta Metro, so i need songs that are from THIS MILLENNIUM. From artists like Beyonce,Alicia Keys, Lil' Wayne, Chris Rock, Slim Shady, Rhianna, SOME stuff from Disney Channel, and some of the Awesomeness of 95.5 The Beat. Thanks. Duces! (for retards, that means bye!)
