When those hard drums came in, accompanied by the triangle-sounding things, I got hooked. The trumpets kept me readily attentive. I also really liked that Dr. Dre type synth that followed the drums. The variety you had with the drums was pretty spectacular. In fact, you had variety with just about everything: the bongos, the triangles, it sounded like there two trumpets playing different notes, that synthesizer blending with the trumpet, etc. That variety, plus the hard drums, made the song interesting and kept me listening.
Keep up the variety man! Post your next work too! I'm interested in hearing more diverse hip hop-reggae.
