A landmark album by Pink Floyd is among the 25 recordings chosen as new entries into the Library of Congress' National Recording Registry.
Each year, the Library of Congress selects for the Registry a handful of songs and albums that have been judged to be "cultural, aesthetic and/or historic American treasures." This year, Pink Floyd's 1973 classic The Dark Side of the Moon is one of those recordings.
The Dark Side of the Moon was the legendary British space-rock band's first album to top the Billboard 200 chart, and has sold more than 15 million copies in the U.S. alone.
Other new entries into the Registry this year include The Ramones' influential self-titled 1976 debut album; Cheap Thrills by Big Brother & the Holding Company -- featuring Janis Joplin on vocals; Simon & Garfunkel's second studio effort, Sounds of Silence; The Bee Gees' 1977 soundtrack to Saturday Night Fever; and the Chubby Checker single "The Twist."
