Don`t own any studio mixes.

but I would have to say, in terms of dance music.
I would pick the following 3 albums, which blow away any commercial mix I`ve ever heard.

Underworld - Second toughest in the infants.
Prodigy - Music for a jilted generation
Sheep on drugs - Greatest hits.

Oh actually I do have a commerical mix I`d add to that.
Richie Hawtin - DE9: Closer to the edit.

Oh, and
Routemeaster records - Free the state.

Erm that`s 5.

Well tough, **** you.
