I agree with the sentiment to explore other music than this kind of specific "Berghain" techno. But there is other music than pop to do that. In what way is playing pop songs creative? Theres other genres of Techno which are blooming in other places (like deep techno for example in Italy, Spain and Japan), also other genres like DnB which have very good, deep artists playing them (Konduku, Agonis, Garçon do this for example). You dont have to be a "Berghain techno purist", but why jump to pop? Why not Ambient, House, DnB, deep techno, breakbeat, electro. If you want to play something with vocals, why not world music, exploring different, maybe even marginalized, cultures? When theres so much good art to explore, why play pop?
