Which makes most techno producers worth their salt say, fck you, i'm gonna try and make something different, using sound elements in other ways, experimentation, rather than same old same old.
Its only a lack of imagination/talentwhen it comes to the paint by numbers stuff.

Its only really techno and the more cutting edge breakcore stuff that still tries to push the boundries.
Other genres tend to find a winning formular and stick with it.

(hard) house/dance/nrg/trance etc.
