Drums maybe a little too loud, but it's really a matter of taste, I think..same goes for the bass..nothing really jumped out at me as being chronically wrong with the track, other than it being too fecking short..length, dude..length..it's important..or so they say.
As for which genre..ya got me there..I haven't a clue, tbh..don't really listen to much of this style usually. How about TripDownHopTempo?
Seriously, I'm leaning towards TripHop, as it sounds a bit "too up" for a downtempo track to my ears..but I could be wrong. Regardless, I'm sure somebody more enlightened will let you know in due course.
All in all, I really liked this as it is..it's just a bit short is all. Nice one.
