Oh, I hate to break it to people, but just about 100% of songs from Disney movies completely suck, and they always have.
And while Pixar wasn't owned by Disney at the time, You've Got a Friend in Me is nearly McCartney-esque in its terribleosity. If I were to compile a list of the worst pop/mainstream songs ever, it would be You've Got a Friend in Me, a couple of the worst Disney songs, that Joe Cocker cover of With a Little Help from My Friends from the Wonder Years, and a couple Paul McCartney songs.
