“Harry’s Wondrous World” by John Williams. I like the titular playfulness with Louis Armstrong. This is my favorite of all the wonderful melodies and music scores heard in the Harry Potter films. Oddly it first really grabbed me when I heard it as the theme to the Lego Harry Potter videogame Pablo y Doodles were playing. John Williams has helped put the themes in the heads of another generation.
