Huffington Post: Original Song: "Part Of Your World" from the classic Disney movie "The Little Mermaid."

Cover Artist: Singer Bruno Mars (who previously showed off his comedic chops hosting SNL in October).

How It's Different: Bruno, instead of our favorite cartoon mermaid, performed the song during his recent set at BBC’s Live Lounge. (Also: Bruno's apparently got 30 "thingamabobs" - not 20!)

Why We Love It: Well, it is the best song ever written, according to Bruno.
