Will Ferrell's devoted physical comedy might be the heart of the movie Elf, but Zooey Deschanel's lovely singing voice is its soul. We've got the classic bops, like Jim Reeves's "Jingle Bells" and Ella Fitzgerald's "Sleigh Ride." The standout song on the soundtrack is Deschanel's smoky, sweet "Baby It's Cold Outside" with Leon Redbone. Her rendition of "Santa Claus Is Coming to Town" with Mary Steenburgen isn't on the soundtrack — give it a listen while rewatching the movie!
