So what? Music stopped being good in the 70s? The 80s? early 90s?
You don't HAVE TO listen to crap like Justin Bieber, you simply take the good with the bad. And choose to listen to the good, whilst avoiding the bad.
90s was a brilliant decade for music, the 00s was a good decade for America (Britain didn't have too much going though.) There's always been great music. It just so happens we were born in a generation where we have all that music to our disposal. This thread kind of annoys me.
