First off, that Gwen Stefani song is "The Sweet Escape", not "The Great Escape". Second, I can usually tolerate some of these songs if it's catchy or if it works for a certain setting. "2 Step" and "Lean Like a Cholo" have no redeeming qualities. For my money, "Hey There Delilah" is the worst.
Oh, and for your viewing pleasure, Fergie's new song and Soulja Boy's new song
