Wow nice song.
Loved the intro and that bass. The instrument changes are nice and without them i fear that the song would have been extremely repetitive.
The middle part was really neat when it changed for i think 2 bars if i remember correctly.
This song could have and would have benefitted alot if there would have been some extra melodies and a little variety in the drums.
All in all you did a good job on this song. Good luck with the contest.
