I'm not normally a fan of techno-ish remixes, but the main tune being done with a sitar just makes one rock. It's powerful in the right places, subtle in the right places, and just fits together really well.
The Snake Man theme from MM3 is one of the simpler tunes from the game. I'm amazed that Disco Dan has made a six minute song out of it that doesn't drag on. Very well done, 8/10. I'd give it a higher score, but it's not a jaw-dropper like several remixes on this site *cough-eutopia-pegasi-cough*
