"Why are you at my side?
How can I be, any use to you now?
Give me a chance, and I'll let you see how
Nothing has changed"
In my opinion, your quoting of these lyrics only stresses that the song is another generic ballad purposely written so it could stand outside of the movie and win an Oscar for Best Song. But on the other hand, I wouldn't be surprise if it's at least partly a trunk song.
