When Sergio comes by with a new artist we MUST listen to immediately, we pay attention. His new obsession: Natalia Kills' new single featuring mega-producer will.i.am.

And because he loves you all so much, Sergio hooked up a link to the song "Free" exclusively for MC readers. Check it out here and come back and tell us what you think!
