Game Breaking Bug - Shadow Mystic Melody

[Tails' Cash Explosion]

I obtained Shadow's Mystic Melody from Stage Selected Sky Rail, 1st mission and then prompty quit the stage immediately afterwards. I then went to White Jungle to complete the third misison but Shadow didn't posses the Mystic Melody and would only say "Huh, no thanks." So I returned to Sky Rail 1st mission but Mystic Melody isn't there to be picked up...

So what do I do? Am I seriously screwed over now because I was halfway through getting all the emblems. I'm not doing this again. Already did it once on Gamecube.

Sky Rail doesn't have the Mystic Melody. It has the Ancient Light. Final Chase has the Mystic Melody.

Oh my gosh really...damn ok thanks haha. It's been too long. I don't even know what Ancient Light does haha. Thanks! I'll go there then.

The Ancient Light allows you to use the Light Speed Attack by charging a spin dash and releasing the action button.

Thanks a lot man, for the help. And now I know why I don't remember that, I recall only one room where that was useful in Crazy Gadget...I think. Oh well. Onward to all 180 emblems. Have a good day!
