OK.
This was pretty good but I must point out a few errors with it... first off, you had a wrong note! that may have been intentional, but personally I don't like it. I really like it when the main melody stops and the beats and bass are going, great, but the rest was a little messed.
The second thing you didn't quite get down was how long it took to build up to the main part with everything goiing. It seemed like you would reach it... then you didn't... then it seemed like you would again... but you didn't.
Good work though hope to be hearing more from you if you wanna hear how popcorn sounds check mine out
