Editors’ Notes Movies from Walt Disney Studios have given the pop canon some of its most unforgettable songs. The studio’s first offering, Snow White and the Seven Dwarfs, spawned a slew of them, including the titular miners’ sprightly workaday anthem “Heigh-Ho.” This collection gathers that and other massive tunes from the studio’s 20th-century animated and live-action blockbusters, including Cinderella’s gently magical “Bibbidi-Bobbidi-Boo,” Toy Story’s shuffling “You’ve Got a Friend in Me,” and Mary Poppins’ gleefully tongue-twisting “Supercalifragilisticexpialidocious.”
