Toccata and Fugue in D(ance) [Insert Bach related pun]
Very cool idea! I was surprised at how well the piece fit into the whole dance song aesthetic. A few thoughts:
It took a pretty long time for the song to get going. Maybe you kept it long as respect to Bach's masterpiece, but I think two minutes and twenty seconds is too long of an intro to a dance song.
Second, and this is little, the octave jumping stuff around 1 minute sounded a little weird to me. It might be the crappy speakers I'm using, but the low note really stuck out from everything else. Just a small thing I noticed.
Again, very cool idea and good execution!
