A bit annoying.
Many of the percussion samples are very annoying. The melody that comes in there sounds off key a lot, im not sure if that was intentional or not. I agree with sirtom in saying that despite it's annoyingness, there was a lot of variation. It needs some work though, because the drums sound like a MIDI set to me.
8/10 and 4/5.
