The fact all this 'offensively average' music is floating around, isn't that bad at all.
Would you rather have unoriginal, boring, sounds-like-eveyone-else mad, cut and paste electronica coming out of your radio? I know I wouldn't.
AVERAGE, SAMEY Arctic Monkeys/Libertines rip offs are much, much better than average, samey <insert large electronic band name> rip offs. Its music that doesn't challenge the listener. That's what radios want, and that's what people want from their radios.
Boundary breaking is often shit and is not called for ALL THE FUCKING TIME.
