Using that vocal sample as an intro does so much for this beat. It only last for about 12 seconds, but it gets me so pumped up, man.
Speaking of the intro, I'm kinda disappointed the instrumental went in a different direction that I thought it was. I dunno what that was in the beginning (guitar?), but it was going pretty fast, so I expected a fast beat. And once the real beat kicks in, everything slows down. Of course, it's still a great beat, it sounds amazing, but that intro threw me off completely, and I kinda wish the rest of the beat built onto that guitar thing.
That aside, everytime I play this, I imagine it being used as the menu song for a Western-style game (and it looks pretty cool in my head, if I do say so myself). Some of your other beats sound like they can be used in games, too (Clockwork sounds like music for some Mines level). It'd be interesting in hear them used on some of the flash games uploaded on Newgrounds, I think.
I'm rambling. Long story short, I llike this.
