This song is a smash!  Whether you saw an awesome choreographed routine on So You Think You Can Dance, saw the band do a so-so rendition on the results show or even heard it in the season premiere of The Hills (whooo hoo! - perfect song for the LC/Heidi fight) --- there is no denying that this song is a hit. 

Watch the music video - enjoy (I posted to the left.)  Timbaland has hands of gold.  You can find his version on You Tube as well...
