I've said it before, i say it again...we're all getting old, hahahahaha.
When rock came out, the same question was posed by the oldies of that time.
And with every new generation, the generation before asks the same question.
and in the end, the generation whose music was labeled as bad by the preceding one, will ask it of the incoming generation's music.
and yet music will go on. har!
You'll only know if the music is really good when it stands the test of time.
