CD only contains 2 cuts, the vocal, then musical version of happy. I'm not complaining though. The lyrics and Pharrell Williams' interpretation is excellent, happy, and fun. It's the first song up in my cars cd, a good start to a good day. I first heard it in a car commercial, it was so upbeat I googled it immediately to see who was that? I had never noticed Pharrell before, but he's sung with Snoop Dog and a few other people before he blew up with happy. It is happy.
Honestly, if this song doesn't put a smile on your face and make your body move to the rhythm then you need to lighten up. Just tap your feel and kinda sway. I would dance in the street, on the sidewalk or anywhere else if I heard this song playing on the street.
