Fine China – Rock Can't Last Forever lyrics

so i heard you got a punk band
what's so punk about that?
and so i heard that you got lots of songs
well friend, nobody cares about that
and everybody needs to learn to get over it, and everybody needs to learn
rock can't last forever
it's just a fad, don't ever try and make it your life
i listened to the tapes you gave me
and i honestly tried not to laugh
and now you say that i'm a meanie
tell me, what's so mean about that?
