Looking for help here, I've gathered a few of the many period tracks from Mario's Time Machine's PC soundtrack and I am unsure whether these are original compositions or arrangements of pre-existing music (like how Ode to Joy for instance is arranged for "Vienna, 1824 AD")

The Bowser's Museum/Castle theme has an odd quirk I found out while recording

Normally it plays through three short songs and then loops back to the first. However, for some reason, the first song gets messed up upon being looped

(Music by Rob Wallace)

Just finished recording the first few tracks, here's the time travel surfing minigame theme! As expected it's completely different from the more well-known SNES version

(Music by Rob Wallace)

I figured out a way to rip the game's music!!!!!

Here's the song used for London in 1843 AD from the PC version of Mario's Time Machine

(Song composed by Donald S. Griffin)

Wouldn't even be surprised if this rodent has them swapped on odd days

This actually happened while playing Kirby Super Star btw
