Just wanted to add in more songs, but anyway hope you'll like this article :)

When I first heard this song I instantly thought of Snow White, it's mainly the happy feeling of the song that makes me think of her

I don't know exactly why, but this one makes me think of Snow White a lot, at first I thought this one suited Aurora and Belle the best, but the fast speed of it made me think of Snow White instead, seriously this one could suit pretty well into the Silly Song scene. This one could also suit Rapunzel quite well in that sense, but it has a more classic feeling to it imo

Can't believe I forgot to add this song in the original article, this one actually suits Snow White quite well

link - Julie Andrews (The Sound Of Music)
This one reminds me a lot of With A Smile And A Song (which happens to be my favorite Disney Song)

link - Within Temptation
I almost forgot to add this song, this one also suits Snow White quite well
