(WASHINGTON) -- Classic recordings by the Bee Gees and Simon & Garfunkel have been named to 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, the Bee Gees' 1977 soundtrack for Saturday Night Fever is one of those recordings.
For many years the biggest-selling soundtrack of all time, before it was eclipsed by The Bodyguard, Saturday Night Fever topped the charts for 24 straight weeks, won several Grammys and spun off a string of hits. It also helped popularize the disco phenomenon worldwide.
Also being added to the Registry this year is Simon & Garfunkel's 1966 album Sounds of Silence, the duo's second album, which included hits like "The Sound of Silence" and "I Am a Rock."
Other new entries into the Registry this year include Pink Floyd's The Dark Side of the Moon, the original cast album of South Pacific, Chubby Checker's "The Twist," Cheap Thrills by Big Brother & the Holding Company -- featuring Janis Joplin on vocals -- and The Ramones' self-titled 1976 debut album.
