What games did you feel had the best music? What games had the most memorable music? Which games had the worst sound tracks you've ever heard before in your life? Also feel free to discuss remixes (OC remixes or other).
I'll start off by saying that the Zelda and SMB themes are probably the most recognizable themes in the world. Zelda also has some great music (village theme, some dungeons, etc). Friday the 13th, for NES, had a very catchy tune although it quickly gets annoying. And of course, let's not forget all of the songs in the Final Fantasy series. If I had to guess, I'd say FF6 had some of the best game music, ever. Some of those themes are just plain awesome.
