love it
i like the hip hop/rock fusion quite a bit, and i think you should do some stuff like this more often. one piece of advice i'd give, is rather than using Slayer, you could use a good piano VST and use an amp simulator on it. it still won't compare to a real guitar, but it will be better than Slayer, and if you don't play guitar, then this may be the next best thing.
but there are also some decent guitar VSTs out there. Sorohanro made a VST that comes with multiple different instruments, guitar being one of them. here's a thread he made recently to advertise it. http://www.newgrounds.com/bbs/topic/1 175105/1
anyway, i loved this song, and hope to hear more like it from you. i'm a huge rock fan, but i also like your hip hop, and rock/hip hop fusion has always been a hit with me. good work.
