The selections span from 1918 to 1980 and were chosen for their cultural, artistic and historical significance.
"Congress created the National Recording Registry to celebrate the richness and variety of our audio heritage," said Librarian of Congress James Billington in announcing the selections.
The recordings include Simon and Garfunkel's "Sounds of Silence," and Chubby Checker's version of "The Twist."
Pink Floyd's iconic "The Dark Side of The Moon" received the highest number of public nominations for this year's registry. The library said it was notable as an example of "brilliant, innovative production in service of the music."
Other selections that made the cut this year include "The Disco Classic," Saturday Night Fever," and a 1940's recording of "You Are My Sunshine" by Jimmie Davis.
