Sonic CD Early Prototype Music Samples

In the 510 Sonic CD Beta deep inside the rom lay hidden multiple music samples of each zone. All except each zones past songs, these songs were most likely early samples of the levels music. Pretty interesting how different some of the songs sound from their final counterparts. They are short samples and all the songs are from the Japanese Soundtrack since the game was made in Japan and then Westernized after it was already completed.

Some of these were used on the 2011 release.

I like them.

I've heard 1:34 In-game before at the end of Stardust Speedway Bad future. This one just might be slightly altered, or just be counted as unused because it was used in the end of the song instead of the beginning as intended

@vampstudios Sonic Retro has these as a part of their Sonic CD Looping Project
