Hey, that's some good s**t right there! I don't want to be cancerous and just say that it is good, so here is some feedback:
The environment - You really did a good job, making the police sirens and the chatter. The only thing that I would personally improve is making the part a little longer and the chatter less decipherable. Yet again, just my opinion.
The actual song - You did a great job with the song, the song is catchy and very ambient, but still electronic. I would just tweak the song notes a little, because some of the notes are a little too high or too low-ly pitched. The drop is... uh... a drop alright. Just some more instruments would have been more enjoyable. That's all.
Summary - The song is a great ambient-electronic hybrid, and you gave vibes that I thought Xtrullor could only give. You really did make a fabulous song, and for that, you are rewarded with a rating of 4.5 stars. Keep it up, CSX!
