We've had tons of these sort of threads. I really can't say which one is my absolute favourite, though "When You Wish Upon a Star" is most certainly up there. Yes, it's a clichéd choice, but there's something so beautiful about it; it's melancholy yet like a wishing star, it captures the spirit of hope in a world of darkness. Other absolute favourites include "Under the Sea", "Part of That World", "The Second Star to the Right", "You've Got a Friend in Me", "You Can Fly", "Love is a Song", "Beauty and the Beast" and "Friend Like Me".
And for the hell of it, I'll list my favourite song from each animated classic at this point in time, though I will skip some of the package features and those that don't really feature that many, if any, songs (and also I'll include the few Pixar films that have quite a number of tunes, as well as some combo films, if the best song in question has some animation set to it):
