The electro/disco approach you adopt here works pretty darn well. The slower tempo you selected is perhaps unexpected given the “disco death race” you’re seeking, but it does have a pulsing insistence I like.

The vocals fit into this, and you wisely create some variations and spaces in the latter part of the mix. I believe it is better to have this at 5:00 or less, although I will have to go listen to the full remix at your myspace to properly opine on that.

This one sounds good. The subtlety you bring to it keeps it from being just another electronica overlay.
