It was tricky finding clean voice samples, and I know what you mean about some people not being too keen on them. I felt the ones I picked were fitting, considering who the song became a tribute to.
I wasn't 100% happy with the volumes either, though I think that was because I kept going back and fiddling with the synths I was using and just playing by (amateur) ear. Pyramid of sound, eh? New concept to me! In all honesty, I never did get into the theory side of music, but I shall remember this from now on!
Thanks
