In recent years, only beaten by Kristen Bell's live performance of Do You Want To Build a Snowman. Classics such as A Whole New World, Can You Feel the Love Tonight and Circle of Life are still better.
Lion King and Toy Story had better from our point of view but at the end of the day it'll come down to which generation you're from and which one was a part fo your childhood.
Toy Story had an awesome soundtrack. <iframe width="640" height="480" src="//www.youtube.com/embed/XHFy3YWpRx8" frameborder="0" allowfullscreen></iframe>

But this is clearly the best Disney song. <iframe width="640" height="480" src="//www.youtube.com/embed/ZSS5dEeMX64" frameborder="0" allowfullscreen></iframe>
