I like the upbeat mood and the catchy beat. The transition at :39 was a little sudden. I would suggest at least using a little reverb to smooth it over. The main problem with this piece is that it's clipping like mad. I think you need to turn some volume levels down so that the final product doesn't sound so harsh. I also don't think this is a structurally complete or well-varied piece. The refrain (:51) is only different from the lead-up in the instrument you used for the chords and the vocal samples. I'd like to see you add some melodic content there to make a stronger sense of progression. Other than that, it's a pretty cool track. You clearly have a good sense of rhythm and harmony. The clipping is the one big fix. Keep at it, man!
