It was short, but you used many effects in just one song. I liked it.
I can tell you're no novice at this.
Yo! Make some more similar to this!
Sure is London's Finest! :D
I think that this song is very well done. The melody did get a little annoying, but that's ok. I still like it.
Again, you have impressive beats. I'd like to see you increase the volume of the kicks(?) a bit, but it won't matter.
P.S. if you decide to make a London's Finest 4, just remember to increase the kick's volume. It'll make it better than it already is. Cya later man.
Sorry bout the melody, and next time I'll make the kicks louder.
