When playing the Sonic 2 Nick Arcade proto, in GHZ I immediately noticed something strange in the music. I dumped a very short .wav of it, and after sitting around on my HD for months, I finally uploaded it here. This “strangeness” is a short “ding” in the music. Trivial or not, I think that it's interesting, because none of the other music (that I listened to from that proto) had any glitches. I could be wrong, though.
