I need help on a cool song kinda  It goes liek    This is the part of the song where its quiet then its kinda quiet intsruments then he goes this is the part of the song where its lounder or somthin and its loud like rock music.

I think its like the grudge song or somthing  any help on the name of it?
Please

Perhaps "The Grunge Song" by Weezer?

This is the part of the song
That's really quiet
we play very soft
it sounds like a ballad

and this is the part
where we play real hard
it's much louder than at the beggining

and we go back
to the quiet part,again
if the whole song was this way
it would be boring

so we go back to playing loud
it's like the first time
but slightly louder
this is usually the place
where it would be quiet again
but we dont wanna to be
too predictable
predictable
predictable

yes thank you
