Well it's certainly chill. I can imagine it being used in a night time city scene of some film. Despite it's relaxed ambience it also made me feel some underlying menace. Perhaps it's just how deep and potent that bass synth sounds but i really sense some threat underlying this piece. I liked all your melodies and i think you did a good job with at keeping it interesting with the variety of different synths and rhythms that join as the song moves along. Despite the songs repetitive nature i never found myself getting bored with it, rather i just got more and more absorbed. In fact the more i listen to it as i write out this review the more i grow to like it. Very catchy tunes throughout. Only thing i'd suggest is making it loop as it definitely feels like it could holp up even whilst playing for eternity. The fade out at the end's sort of a cop out but then again it's fairly standard with this sort of music for allowing mixing with other songs etc. so i'm not sure if i can complain.
I'm rambling now so i'll stop and say i really have grown to like this and shall be downloading it, putting it in my ipod and playing it my car when i go out driving. Great work!
