There's also the Sega Ages port for Saturn, although I have no idea how that compares. It's in redbook audio format.
Of course, if you really mean the "original files", that's a bit trickier. Columns 2 (and the Sega C-2 board in general) doesn't seem to be supported in M1 or Hoot, and I highly doubt you or anyone else here has the time or patience to unearth the music data from the two 131kb files that make up the game, then figure out some way to play them accurately, just for this request. Sorry.
