Our friend Nick Cannon is rolling out the third episode of his brand new countdown show this week, and we’re airing it here! Check back each weekend for the countdown in full.

I’m back for a third amazing week on Cannon’s Countdown. Get ready for a party because I’m blowing the roof off this joint! (Quietly, the babies are sleeping). Whatever your jam, I got something hot for you. So get ready. I’m breaking down all the hits right now!

30. Selena Gomez and The Scene “Who Says”
Wow! What a way to kick off the countdown. Selena’s “Who Says” has over 26 MILLION views on Vevo. It’s just rolling into the countdown and getting airplay across the country. Selena is so much more that Bieber’s girl. “Who Says” she can’t be more?

29. Martin Solveig and Dragonette “Hello”
Check the door. Who let hipsters into this week’s Countdown? Meet Martin Solveig and Dragonette. I predict right now, you will hear this song all Summer long. Just remember who told you about it first. Game on!
