I’d just subscribed to Disney’s channel on YouTube few months ago, when Frozen would be released. I watch some videos and getting curious with the story. When the channel released the OST sung by Demi Lovato, I immediately fell in love. Then I also watched the same song with different singer (Idina Menzel, the voice of Queen Elsa). Her voice is very powerful and beautiful. I really like it—touching and moving in the same time.
