really a beautiful song do you know the singer POOHsie
"Little Wonders" by Rob Thomas from the movie "Meet the Robinsons" always get's me a little choked up!
So many, but usually it's reprises or instrumentals that move me the most. I love the music in Beauty and the Beast and The Little Mermaid. Even just the opening scene to The Little Mermaid when you first see the underwater palace makes me well up! And the Part of Your World Reprise is one of the most beautiful things I have ever heard.
As for specific songs, maybe The Circle of Life or Colors of the Wind? Oh, and When You Wish Upon A Star.
