My only complaint with this song is that the bit between 2:34.62 and 3:03.72 (yes, I found exact timings) doesn't fit very well, it seems less melodic than the other parts. Other than that, it's one of the best songs on newgrounds!
(if anyone who isn't the creator happens to agree with this, you can just cut the area between those two timestamps out with audacity, I made sure that the cuts didn't interfere with the beat and sound smooth)
Best drop I've heard in years!
Please contact me if you would like to use this in a project. We can discuss the details.
