Some of the mixing could be done better. The crash seemed really out of volume placement at times, and some of the instrument choices weren't very good. But it's catchy in a wierd way, I almost liked the bass part, it's tight. The drums could be improved. And by the by, there is NO FREAKIN WAY this is 270, your bass drum part determines that, you'd have to double 135, the tempo this is at now, to get to 270, the eight note tempo = 270, but the normal quarter note tempo = 135. You've got to think on that one before using it as an advertising ploy, lol.
-Good job, check my stuff and rate it.
