Last month, an Eagles album from the 1970s — "Their Greatest Hits (1971–1975)" — was certified quadruple diamond, the first to sell more than 40 million copies, cementing its place as the best-selling album of all time. "'Greatest Hits' is kind of a misnomer,” the band's co-founder, Don Henley, told Tracy Smith. “It should just be called their best songs because every song on that album was not a great hit.” https://cbsn.ws/4r7mhfy | CBS Sunday Morning
