Another smash hit in a long list of hits, another guilty pleasure from Maroon 5.
Adam Levine and Christina Aguilera come together for what could be the catchiest song since Katy Perry's California Gurls. Adam's sinewy voice slides up and down the scales backed by the most tasty ear candy whistling hook ever recorded. Just when you think you've got the bulk of the song and know where its headed, Christina jumps it and adds the grit. Wish there was an alternate version without the admittedly minor four letter word. I won't buy it because of this- until its edited, but I gotta say, the song's terrific.
