1 thing I do blame it for is ruining music! When Napster created the 1st download music site, they probably didn't think about the long term damage it would have on music & bands down the road...

This is 1 of the reasons why music became so terrible over the past 2 decades! Crap that sounds like absolute garbage; is what's considered popular these days! It used to be when an album became Gold or Platinum, it earned it in sales!
