I think it means before Linkin Park got popular they struggled to even get signed. So in the song Mike raps about their struggles and how nobody wants to listen to them. :chaz:
i think that nobody's listening means when you get in trouble or you get in pain and you would like to talk about it with anyboby but in reality nobody cares. so nobody's listening to his problems...
I actually think it's about when u want to warn sb (try to give you warning) but he doen't listens, and in the end he gets in trouble, even though u' ve done everything to protect him. :chemist: The Shakuhachi flute rocks!
