Not every Disney movie (animated) is a musical- Black Cauldron, Rescuers Down Under, Dinosaur, Atlantis, Treasure Planet, Chicken Little, Home on the Range, Meet the Robinsons, Bolt, Big Hero 6, Zootopia, Strange World, Raya. Wreck It Ralph, Ralph Breaks the Internet are not musicals. I might be able to think of more.
Which is what I assume you mean by no song because my family sings quite a few Pixar songs all the time- Can't Let You Throw Yourself Away, We Belong Together, Time of Your Life, Steal the Show, and Carried Me with You are HUGE favs in this household.
Edited to add: 101 Dalmatians is also not a musical even through it has a great song in it. Bambi has lots of music but it would be closer IMO to how Pixar does music. The characters aren't singing. Fox & the Hound is the same. Emperor's New Groove also not a musical (was supposed to be and that doc is worth watching).
