Twinkle Twinkle makes list!

Every year, the Library of Congress designates 25 sound recordings "cultural and historic treasures" and it preserves the best available copy for future generations. This year's choices, announced Wednesday, include an 1888 hand-cranked recording of "Twinkle, Twinkle Little Star"; Prince's "Purple rain," "A Charlie Brown Christmas"; and one that caught our ears….

Edward R. Murrow was the narrator for "I Can Hear It Now," a Columbia Records recording that was selected by the Library of Congress as a cultural and historical treasure, announced May 23, 2012.
