The Library of Congress' National Recording Registry annually adds recordings that are “culturally, historically, or aesthetically significant” and preserves them for future generations. This year they added recordings such as "I Feel Love" by Donna Summer, "A Charlie Brown Christmas" by the Vince Guaraldi Trio, and "Rapper’s Delight" by the Sugarhill Gang.
See the full list of new additions to the National Recording Registry.
