I could see Pocahontas, Belle, or Mulan singing it :)
I picked Pocahontas because I think she is the most selfless of the princesses and the song relates to her very well <3

Here are the lyrics if anyone is interested:

Hmm, never heard this song, but from the lyrics I'd have to say Poca. She's pretty much experienced and had to get over everything listed in the chorus, and would wish that everyone would be able to do the same.

"No more lives torn apart"- Kocoum died and many lives must've been affected by that. Poca would have had to witness it all.
"That wars would never start"- Um, she kinda stopped a war from breaking out xP
"And time would heal all hearts"- since she and John didn't exactly end up together, her heart had to mend with time.
"And everyone would have a friend"- Nakoma always stood by her and only ever tried to help
"And right would always win"- It wasn't right for John to have be shot.
"And love would never end'"- THE SEQUEL. That's all I'm saying. THE FREAKING SEQUEL.

What about a "Never heard that song in my life" option?

^ I put a link to the lyrics in my 1st comment so if you're interested you can read them and get a feel for what the song is about :)

Or Mulan!

Ew, Kelly Clarkson. Hate her so much.

I like her. I appreciate that she can actually sing unlike most singers in the industry right now. Also like the fact that she isn't as thin as a toothpick.

Agree with firegirl1515 - never heard the song but based on the lyrics, Pocahontas. Possibly Mulan.

Thanks so much for mentioning this lovely song. Didn't know of its existence until now.
