Great article! Opinions of course are going to differ form person to person. Man, I loved the Boss Theme, so I disagree there. I also really, really loved Chill Penguin's theme. I thought it fit the ice stage perfectly. You don't want too much intensity for that stage. Actually, come to think of it, you and I disagree about the whole "mediocre tracks" thing with the exception of Sigma lvl 2, which I agree is a bit bland compared to the rest. I'd also throw in there Boomer Kuwanga's level theme, which I don't find to be as good as the rest (too cheesy, and you nailed it comparing it to Rocky). Otherwise you're spot on. This album, this whole game, is easily one of my favorites.
Definitely in the top 10 best soundtracks for the SNES.
Absolutely. It might even grace my top 3.
Also, nitpicking here, you probably want "memorable" and not "rememberable".
