DUDE I LOVE IT!
Im curious what software u used for this cuz i love the instrument pack. I use fl studio. Although i have to say the piano in the begining was kinda hard for me to flow with but the rest was beast!
Thanks :D I use Fl Studio too, most of the sounds are from the Nexus plug-in.
The drums are from VEC3. Hope it helped and the piano part... I noticed that after I had made the song, but I never really did anything with it XD
