We hear the first line of this banger at Jackson's mic check for the concert where he and Ally sing together for the first time. However on the soundtrack, "Diggin' My Grave" is a duet between the two. Lady Gaga is an absolute powerhouse on it, and Bradley's gruff voice is the perfect base. As we unfortunately come to find in the movie's final scenes, the two truly were digging each other's graves, both figuratively and literally. Their tumultuous relationship is summed up in the line, "You're just another nail on my, my coffin lid."
