I believe that this song has nothing to do with a girl at all. I think this is Chris saying that he is sick of who he is. Even in the title, "Jukebox Breakdown", he makes a symbolic comparison to music. "Put a quarter in my neck" = you pay me to sing for you. "I'll sing a song for whatever mood your in" = we listen to saves the day for the lyrics that relate to our moods. "Isn't that what you expect?" we basically expect Chris to "carry our crosses" for us. "All you want from me is a broken heart and a mouthful of blood" we want him to sing songs that describe our hatred like rocks tonic and as your ghost takes flight. This is a song about Chris realizing he is a puppet to the fans and that he does everything for us.
