Somewhere, out there, is a band that has not done a cover of Royals. Bluegrass, Black Metal, Glitch, Tuvan Throat Singing; every musician in every known musical style has done at least one YouTube video of it. Members of the Ava-Canoeiro tribe, an uncontacted people indigenous to central Brazil, have been recently observed performing the song as part of a fertility ritual. The only musician not to cover of the song is Lorde herself, as it would be, by definition, not a cover. Scientists are working to overcome this by cloning the singer, thus creating a Lorde who is sufficiently not-Lorde who could then cover the song.
