Given the 'qualities' of the tripe coming out of our music industry is it any wonder? I look at the dregs who produce our music these days and find myself appreciating the muslim intolerance for the social influences of Bono, Madonna, Elton John, any number of rappers, & etc. Perhaps not all of their (muslim) opinions are necessarily flawed.
Regarding the "quality" of contemporary western "music" I agree with you, and there is certainly a valid point in blocking this garbage, but I suspect that in those Islamic tyranies it's more about control of the people than anything else.
