i dont think its money. i think its natural that after xy years you are changing your approach towards music, your preferences etc, people change, and so is their music
and i wouldnt really call everything joris plays house music, there's plenty of techno in his sets, only slower
besides, so much music out there is so hard to categorise and if its good i dont really feel the need to do it anyway, i'll rather spend my time enjoying it... its really bad/sad to be limited to only electronic music, or even one subgenre... imo limited people shouldnt be dj-ing anyway
ps. interesting how people were hating on richie when he said his computer does beatmatching for him, but not a single word when joris mentioned it hehe
