I made the poll list mostly based on Wikipedia's soundtrack. It's the first time I've seen Dig-a-Dig Dig separated from Heigh Ho! and it made me realize they are two separate songs just like One Song and I'm Wishing, except Dig-a-Dig Dig doesn't even get equal acknowledgement along with Heigh Ho like with those two.
1. "One Song" ~ I love the part of the film when the prince sings to her. It's why I always prefer Snow White's prince to Prince Charming and even Phillip, despite the animation for him leaving... Something to be desired. I love the singer's voice, too, very warm and strong.
2. "I'm Wishing" ~ My favorite of Snow White's numbers. I don't love the way the voice is sped up, but I don't really hate it as much as others.

I really like Snow White the character; Aurora's the only one of the three Walt princesses I don't care for, although the character is beautiful in her blue dress.
3. "Dig-a-Dig Dig" ~ This and "Whistle While You Work" are the biggest earworms of the soundtrack for me. They're the ones that will come to me at random moments. "Heigh Ho!"'s good, but I prefer this a great deal to that (another reason I wanted to separate them).
4. "Whistle While You Work" ~ Like I said above, this one comes into my mind randomly at times, particularly when I'm doing housework.

"A Spoonful of Sugar" does the same thing.
5. "With a Smile and a Song" ~ This is the one I most easily forget until I watch the film, but I enjoy it and it has a nice melody. I wish the Legacy Collection hadn't ended, because I would've liked to have bought a Snow White soundtrack through them. I have most of the songs via compilation albums like many other of the older films (like Sword in the Stone and Bedknobs & Broomsticks), but I don't have this one. I do have a version of it included on the Heigh Ho! Mozart album though, which I'm listening to right now.
6. "Heigh Ho!" ~ It's one of those iconic songs, like "Bibbidi Bobbidi Boo."
7. "Someday My Prince Will Come" ~ Snow White's main song is actually my least favorite of hers. I don't hate it, and its not because it's a song about longing to be rescued, I'm simply not crazy about it is all. I probably enjoy watching it as a scene more than listening to it divorced from the film, with how all the dwarfs are mesmerized by her.
8. "The Dwarfs' Washing Song" ~ I never listen to this outside the film. Still, it's one of the funniest moments in the movie to me.
9. "The Dwarfs' Yodel Song" ~ This is the reverse of the washing song. I always dislike this part of the movie... Well, maybe "dislike" is a little harsh. "I'm bored" is a better way to describe this scene.
