Twenty-five recordings were selected for preservation at the Library of Congress in the National Recording Registry, and Simon & Garfunkel's Sounds of Silence made the cut on Thursday.

Also preserved in the Library of Congress is Chubby Checker's The Twist, The Bee Gees' soundtrack for Saturday Night Fever and Pink Floyd's album The Dark Side of The Moon.

Songs are chosen to be preserved because of their cultural, artistic and historic importance, according to The Associated Press. Sounds of Silence by Paul Simon and Art Garfunkel was written after the assassination of President John F. Kennedy and didn't become a hit until it was re-edited and released as a single, according to the AP.

Garfunkel, 71, told the publication that he was flattered that the song will be preserved. The song's lyrics were noted as having significance in American culture.

Garfunkel said of singing the song, "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."

The selections spanned from 1918 to 1980 and Librarian of Congress James Billington said of the songs selected that they are "to celebrate the richness and variety of our audio heritage," according to the publication.

The library said Dark Side of The Moon was chosen because it was an example of "brilliant, innovative production in service of the music."

The Twist was considered a symbol in the early 1960s of energy and excitement.

Each year since 2000 the registry adds 25 songs, accoridng to BBC.
