"Rob's Party Mix" or "Cloverfield Mix" is a collection of the music played in the opening party sequences of the film that was released exclusively on Apple's iTunes Store on January 22, 2008 in lieu of a traditional soundtrack album. The "Cloverfield" score, "Roar! ("Cloverfield" Overture)" by Michael Giacchino that plays over the end credits is not featured on the album, as it is the mixtape played at the party and is not the official soundtrack of the film. This album was distributed to guests at a "Cloverfield" premiere party held at the Dark Room in New York City on January 17, 2008.
