Stay on track!
As much as I like variety, you kinda messed it up on this song. It started out perfect, but during the last 1/3 of the song it went from "Awesome start!" to "WTF IS THAT NOISE?!"
Eventually you got those noises organized into a 'sloppy' beat. But I admit, even with that weird sound at the end, it deserves a nice 4.
