Bawz I'm with Tony. There is a huge diffrence between techno and hard trance, scouse house or whatever is on that website, they are not the same thing, it would be like going into a car dealer to get a Ferrari and finding some second hand Ford Ka's lined up with a nice buffing of waxing on it.
In fact the very fact of promoting something as techno, when there isn't any techno in sight kind of says to me "Hi there, I really don't know what I'm doing" and looks veryunprofessional, I mean would you really think you really think to go buy techno records from www.trance-tunes.com
Maybe a bit of rebranding is in order here to sort out problem with the images presented and you could always split up the sites into allowing the user to select between whether being presented with a selection of techno only or or styles seperately.
