I thought it was a very fun and up-tempo song, for the most part. Definately made you want to do something. The onle thing I would change wouldn't be so much about the music as a whole, but the intro. I think that instead of keeping it so similar the WHOLE way, you should put in something a little more half and half, like the sound at about 3 minutes, part way through the intro to break the repetition a little. Good song!
