Chris Stapleton just reached a milestone that no other country artist has ever reached. His recording of “Tennessee Whiskey” was certified double Diamond yesterday by the RIAA (Recording Industry Association of America), signifying more than 20-million units sold. It’s one of the rarest achievements in music; the first single ever to be so recognized was Post Malone and Swae Lee‘s “Sunflower, in February 2024. Drake has also scored a double Diamond single, with his 2017 single “HUMBLE” reaching that milestone last year.
