FIRST!! But really, Good song!
The one problem I had was you stuck with the same beat too long. Then when it finally changed to a new one, it was just as long, never changing. The second beat wasn't very good either, it seemed scattered compared to the first one.
But besides that, great! You switched instruments and even though the first beat was carried on for so long. It was a FKing awesome beat, so I can see alot of people 'not minding' that it looped for so long.
