Based on the lyrics, I pick Snow White or Aurora. They are both serenaded to by their prince when they first meet so I think the lines "But you sing to me over and over again.... Sing to me the song of the stars, of your galaxy dancing and laughing and laughing again. When it feels like my dreams are so far, sing to me of the plans that you have for me over again.... I want your symphony. Singing in all that I am. At the top of my lungs, I'm giving it back." I think this is most descriptive of "One Song" but also representative of dancing in the forest to "Once Upon A Dream". Both of these DPs were put under a spell and their only hope was their true love's kiss so I think it would fit them both really well. By the way this is absolutely a beautiful song and Mandy Moore's voice is beautiful in it. Thanks for reminding me of it, dee389!

Your welcome!!

I've liked this song for a while now. :)
