What are some good new songs for summer 2011?

i am a teenager looking for some good NEW songs for summer 2011. Obviously would like them to be either of rap, pop, hip hop, techno.. you know, pumpy songs. I like nicki minaj, drake, chris brown, daddy yankee (i am Spanish so i love Latin songs.), rihanna, lil wayne, wiz, don omar, akon, inna, david guetta and lots more.
