1. Adele, "Rolling in the Deep"

2. Katy Perry featuring Kanye West, "E.T."

3. Lady Gaga, "The Edge of Glory"

It's a song about Lady Gaga's late grandfather and the celebration of life in the face of death. While not quite the seamless blend of power ballad, smooth jazz, and electropop that it's been marketed as, the single has a moving theme, synthesizers that sometimes work, and a great saxophone solo by musician Clarence Clemons.

4. Pitbull featuring Ne-Yo, AfroJack & Nayer, "Give Me Everything"

5. The Black Eyed Peas, "Just Can't Get Enough"

6. Jennifer Lopez featuring Pitbull, "On the Floor"

7. Bruno Mars, "The Lazy Song"

8. Britney Spears featuring Nicki Minaj & Ke$ha, "Till The World Ends"

9. Chris Brown featuring Lil Wayne & Busta Rhymes, "Look at Me Now"
