This has a real nice vibe to it. I dig it. A lot.
Its simple, but elegant. It doesn't need change ups or improvisation because its good the way it is. It just flows very nicely. Would fit in perfectly in with some driving scene out of a modern age "gangstah-flick". But its application is trivial. My main point is that I can just let this play in the background for a least five loops before it starts to bug me, which is quite a feat.
However, even though I did say its repetitiveness is not a problem because its done so well, minor changes are still appreciated. For example some drum fills with some emphasis on toms or high-hats.
Finally, there is one big thing that is keeping this song from greatness. One, it is very short. Two, lyrics (obviously a rap) would of made this song awesome. I have a huge interest in lyrical rap is this is a perfect chance for you to make some.
Make the song longer, add lyrics, come up with a simple chorus, and some simple but needed drum fills, and you got yourself a easy ten star song.
I appreciate the fact that you didn't just make another techno song, and that your song has a lot of style to it. That being said I'm not going to say that its perfect when it isn't like every other reviewer on this site.
Lastly, and I hate to push this but I feel I must because this song has such potential, I have a huge interest in literature. I know a lot of music, and about rhythms. When I mentioned remaking this with lyrics I meant it. I can write them for you if you want them, but I want credit if I do.
I apologize for adding that last bit, but I want you to know that I'm serious about making this song as great as possible. Let me know if your interested in "pushing the envelope."
Oh, and nice song.
