In the Hip-Hop scene exclusive remixes are all the rage on the Mix Tape phenomena circuit - all the big artists have their own 'mix tapes' - 50 Cent, Eminem etc. Hell! There's even the infamous Jay Z grey album - where DJ Dangermouse remixed Jay Z tracks with the Beatles - check the review in Rolling Stone magazine - http://www.rollingstone.com/news/story/_/id/5937152 maybe the techno scene could take a few leafs out of the hip-hop book as hip-hop is at the top of the stack where dance was a few years back.
