That was great.
backbeat was really chilled.
drop wasnt that heavy or bassy, but wow, filthy.
it was almost comedic, dub with a sense of humour, the tune @ 1:23 and 3:00 made me smile.
brilliant.

still think you could do with a change of vocals, maybe start doing covers of other songs.
and start bringing in some whomp over your BZZZZ ZBZBBZBZZ drops, or dropping the bzz just a little bit, gets a bit harsh after a while
