This Is My World is a track from the score for Zack Snyder's Batman v Superman: Dawn of Justice composed by Hans Zimmer and Junkie XL. It is featured near the end of Superman, Batman, and Wonder Woman's battle with Doomsday. The piece enters with a piano motif for Superman, then continues with a somber string ballad accompanied by piano. This latter melody is comparable to a classical requiem .
This track borrows from another, If You Love These People, from Zack Snyder's Man of Steel.
