Lionel Richie, Eminem, and More Memorable Best Original Song Oscar Winners

The super-catchy "Let It Go" — sung by Idina Menzel — from "Frozen" won wife-and-husband duo Anderson-Lopez and Lopez the Oscar in 2014. Menzel delivered a movie-themed performance at the show just before their win.

The song is loved not only by children who adore the movie but also by adults for the complexity of its lyrics.
