"Old People" Music

So I am in the car singing along with the radio. Natalie is in the backseat and says "Mom, Why do we always have to listen to "Old People" music. I was to stunned to speak at first! Old people music?! This is Green Day! Granted I do think the song came out when I was in middle school but still! It was "When I come around". When i think old people music i think of barry manilow, Not Green Day.
