Twenty-five recordings have been chosen for preservation at the Library of Congress, including Simon and Garfunkel's song "Sound of Silence."

The Washington Post reported that the "Sound of Silence" was written after President John F. Kennedy's assassination.  The 25 songs are being added to the National Recording Registry on Thursday due to their important historical, cultural and artistic significance. Chubby Cheker's "The Twist" is another one being added. The Washington Post reported that the congress said that the song became a symbol for the excitement of the early 60s.

Art Garfunkel, 71, said to the AP that he is thrilled.

"When you look at the little mesh, wire microphone ... and you address people on the other side of the mic, you hope that your performance will be special, and you hope that it will have lasting power," he said, adding that he remembers thinking in the 60s that "if we do really good and give a very special performance to these great Paul Simon songs, we might last right into the next century and be appreciated," he said to the AP.

Pink Floyd's "Dark Side of the Moon" had the highest number of public nominations for this year's registry, reported The Washington Post.

The library noted that it was an example "brilliant, innovative production in service of the music".

Other songs noted in the selection include Jimmy Davis' "You Are My Sunshine" from 1940 which became President Herbert Hoover's election campaign song when he was running for Louisiana governor.

"It became one of the most popular country songs of all time and the state song of Louisiana in 1977," added the BBC."The classical pianist Van Cliburn's Cold War performance when he won the prestigious Tchaikovsky International Piano Competition at 23 also was selected. The American musician who performed for every US president since Harry Truman, died in February."
