Back in January, Warner Bros. and Water Tower Music released the full track list for the Batman v Superman: Dawn of Justice soundtrack. Various formats are available: The 2-CD deluxe 18-track package, the digital deluxe version, and the 3-disc deluxe vinyl set feature over 90 minutes of music, five bonus tracks, an exclusive fold-out poster and liner notes from the composers. Additionally, the vinyl set features etched vinyl art and an album download card.
Hans Zimmer returns to the DCEU to provide the score, after working on the 2013 entry, Man of Steel. Initially, Hans expressed reluctance to write the music to Batman V Superman, because he didn't believe he would be able to recreate the process of composing new Batman music after working on The Dark Knight trilogy. On board came sometime collaborator, Tom Holkenberg, a.k.a. Junkie XL, who worked on the Batman theme while, Hans Zimmer continued to craft the Superman theme.
The album is available in digital stores everywhere, as well in CD Format at participating retail stores.
