Although it was produced as a mainstream song, "D.A.F." was released as a single which included their cover version of the Warumpi Band single, "Blackfella/Whitefella", which was in recognition of Australian Indigenous people. Fanning commented on the band choosing to include the song, saying "we don't set out to preach or give social commentary, but we do have the opportunity to put forward an opinion". He also explained that the topic of social justice was one the band felt strongly about, and that the song had "the perfect lyrics to reflect that opinion".
