Here we go:
0:00 diggin' the intro sound...very old school.
0:21 begin kickass section. I really love the feel of this.
0:45 that's a sizzling lead you've got going on there! sounds great
1:07 interesting.. but the transition to this is a little too hard.
1:28 and back to awesome. I hope you're gonna be doing that line with the sizzling lead mentioned above at some point.
1:51 while the transition here was too abrupt for my tastes, this section feels more in line with the song than the one that begins at 1:07. Perhaps the one at 1:07 should mirror this more closely?
2:34 we're into a whole new piece here it feels like. lost the thread of the original source tune. Look at into my comment at 1:28... you should use this lead synth to do the main line from the original song at some point, perhaps instead of this section?
All in all it's extremely funky and I love the tone of it. Production needs a little work, the drums are just a little too messy and they're bleeding into too many other frequencies. Try to sweet spot em up a bit.
DKC2 is my favorite game soundtrack. You are doing a good job at this, keep it up, THIS SOUNDTRACK NEEDS MORE LOVE.
