Seeing someone mention "Twinkle Twinkle, Little Star", kinda justifies my immediate first thought,
even if that music is more meditative.
But I have to type that everything mentioned here so far is pre-new millennium traditional.
The modern includes animated visuals or cinema-photographic content.
So my first thought is, "The Lollipop Song", from "The Wizard of Oz".
And as musical due diligence, "Lickin' Stick", by "Howlin' Wolf" should be the B-side.
Both films take "black and white" to a new "colour" level.
