I know this beat all too well.
Calling it Corruption does not give the track its deserved credit.
You should include this in your comments asap.
This track can be heard on GameBoy Color's version of Crystalis and the 8-bit version can be found on...you guessed it, NES.
I do like the hype you put into it, but the techno feel of this track destroys the feel of the original. Everything is pieced together greatly, a flawless remix to the Pyramid of Seth.
Awaiting to hear your finished work of this piece.
