Sometime recently, Garth Brooks’s 2007 greatest-hits compilation The Ultimate Hits quietly sold its ten millionth copy. Brooks already had six ten million-selling records—his first three studio albums, his 1997 album Sevens, and two additional compilation releases—making him the first artist with seven diamond records to his name.
The Beatles have only six diamond records, though, as Billboard notes, they’ve sold more units overall. John, Paul, George, and Ringo also hold the record for the most number-one singles (20), followed by Elvis and Mariah Carey. Brooks won’t match them there any time soon: Though he’s earned a bundle of No. 1 singles on the country chart over the years, his mainstream chart peak came in 2001 with “Wrapped Up in You” at No. 46.
