maybe they did a special version of the track with a vocal masking effect added so we fuckers on the net can't burn it and sell it............???
Seems like a smart move to me..."release" the remix first so people hear the vocals and start to get into it......then "release" the "real" track, but add lots of effects to a handful of the vocal tracks to mess with us (the potential sonic theives amoungst us mainly), and then finally RELEASE ON CD/DVD the REAL track that sounds like the music from "electronic" with the vocals from "bang the poll" with just a touch of the effects added to the vocals.
At least I hope so.....I can sing into a fan in a monotone voice and recreate the vocals on "Electronic Singer Part 1"
