Bop till You Drop is Ry Cooder's eighth album, released in 1979. This was the first major-label digitally recorded album of Pop music. The album consisted almost entirely of covers of earlier R&B and rock'n'roll classics, including Elvis Presley's "Little Sister" and the 1965 Fontella Bass-Bobby McClure hit "Don't Mess Up a Good Thing", on which Cooder duetted with soul star Chaka Khan, who also performed on the only original track on the album, "Down in Hollywood".
