You Can Fly. Peter Pan was definitely the first Disney movie I saw, if not the first movie ever. Flying over London just had me gobsmacked and the song is so beautiful. Especially "think of all the joy you'll find, when you leave the world behind and bid your cares goodbye..." I was only 4 and I knew exactly what that meant and that I wanted to do it.
Circle of Life. I could have gone home happy after the opening, didn't care for the movie.
Colours of the Wind. Even though they made a mockery of the true story, the song was so beautiful.
Whole New World. Just my grown up answer to the four year old me's You Can Fly really (plus I love Lea Salonga's voice.)
You'll Be In My Heart. Had NO idea where this song came from 'til quite recently.
Let It Go. POWERFUL song!
