Maybe I'm reading too much into the song, but from the beginning until about the "I hate you" part the music is sort of..well, it kind of reminds me of a sort of funeral march. Then, at the "I hate you" part, the music perks up a bit, symbolizing how the star and the fan are really just kids- the music is very playful at that point, in contrast to the seriousness of the beginning.
