All other complaints aside, this, to me, is iTunes' worst offense. I don't know if there was some official standard ever, but it was at a very minimum an unofficial standard for DECADES. Now some asshole designer has decided to muddle and confuse everyone by redefining the symbol. This idea has infected PowerAmp on Android now, too.
I have not seen anyone discussing this before (but I haven't looked very hard). I refuse to buy into this new definition. Am I the only one bothered by this? I can't take a music application seriously if it can't get the symbols right.
