I have to say, if you like the sound of the Megadrive, check out some of the music on the X68000. It's the same kind of beefy FM sound, only up to eleven.
But to get a tad back on topic, it's really quite impressive to realize that pretty much every Sonic game has good music, if not fantastic. The old school 8/16-bit games notwithstanding, I was listening the other day to Sonic 06's soundtrack, and it's really outstanding : extremely well made, beautiful arrangements, intricate work on melodies, with variations on each track (much like the Act 1/Act 2 system of 3/SK and 3D Blast). I was quite floored.
