Dayum.
00:00 - This one sounds very promising the way it is now, I don't think it would require much more polishing to make it a solid track.
00:20 - Very interesting style going on here, I like the square synth lead going on.
00:42-01:18 Trip/Hip hop isn't really my style, so I doubt if I could give any constructive advice about them.
01:45 - Very funky, but I don't really see it going anywhere unfortunately.
03:04 - Bossa nova feel, I'm really liking this one.
04:48 - Psychedelic rock type stuff, you should definitely finish this one :P
05:37 - This one has got a lot of promise, but maybe make the snare rolls slightly longer.
There's a couple of gems in this mix, but also a few mediocre ones. That's not to say that they won't appeal to someone else, it's just not my kind of thing.
