Plus, Opus 13 already existed in DraculaXX, it was a tune that played on Stage 5, I believe.
The tunes that didn't make it to the SNES are Richter's Intro, the Boss AnteRoom music (the SNES version is different and way better), Slash (music from Rondo's River stage), Cross a Fear (Rondo's Bridge stage), March of the Holy Man (Richter's ending), and Mary Samba (Maria's ending), plus the cutscene jingles.
Edit:
Dracula9, your MP3 is horribly low in volume. I can't hear anything even with the thing turned up to max.
