Reflection: link

Let It Go: link

Both are amazing! I prefer Reflection more as a song but I like the music video for Let It Go better because of the direction, the movie clips, and Demi has a better voice. It was really hard for me to choose because they're both amazing. I just realized this, these are the only Disney Princess music videos with former Disney Channel stars.

I prefer Let It Go so much more as a song, but Christina has the better voice in my opinion.

Both are wonderful!
My favorite is
I Still Believe-Hayden Panettiere (Cinderella 3), although it isn't actually sang in the movie, just the credits, I believe.

Christina might have an amazing singing voice but I don't like her version of Reflection.

Yeah ^ I find Christina's voice wonderful, but I love the original of reflection so much, it's hard to beat.

I agree with dclairmont. Please, CHRISTINA has the better voice. And in the Reflection video was the only time that I liked Christina Aguilera, before she started being slutty. I remember constantly playing her version of Reflection because I loved this part of the song: "Why must we all conceal what we think, how we feel? Must there be a secret me I'm forced to hide? " She made the song better, to be honest, because it was longer and added more lyrics that I liked.

Let It Go, I like it for the movie clips and I like the beat during the chorus. I liked seeing Elsa building her castle and I can't wait to see the movie with Idina Menzel singing it. (Who also has a better voice, by the way) I'm not that fond of the "Na na, na na" part.
