The opening of the Menu theme from Super Smash Bros. Melee sounds more than a bit similar to Terranigma's Main Theme. Just a fun observation.

The main character (Ark) has a non-playable companion called for his journey (like Navi from Zelda), which is where that theme plays.

Laboratory does play as a dungeon theme, yeah. If I remember correctly, it also plays in a scene that the Terranigma fan community poked fun at (http://tinyurl.com/yd87z29m).

I might've knocked a point off compared to your review, but that's probably because some of my favourite tracks (like Dark Side Field and Call at a Port) aren't actually played that often in them game itself and that I found the violin sample a bit annoying when I was younger (although it sounds fine now). The compositions themselves are definitely great, though, and definitely one of the best on the SNES.

I didn't actually notice any typos this time, so no correction to make. :p
