i found some sonic 3d blast demo tape music.

so i took a look at the sonic 3d blast demo tape page and it said that nothing was available, yet something was available, in jon's "Top 10 Surprising Sonic 3D Facts (Sega's surprise & disappointment)" at number 5, he mentions 2 unused songs, the one that got used in sonic 4, and a tails bonus stage track,(the demo tape music). at 2:28 it starts playing so ill put the video down here, however, its only part of the music so partially found track of lost tracks.
