National Jukebox
1900’s Music the 21st Century Way: The National Jukebox
Thanks to The Library of Congress and Sony we now have the oldies to enjoy. When I say oldies I mean OLDIES! Scores of original recordings have been digitized and readied for your listening pleasure and made available free of charge to the public on the Library of Congress Jukebox site. The library recordings currently stretch from the year 1901 to 1925 and is expanding; from around the world. There are recordings ranging from ethnic characterizations, monologues, classical music, popular music, religious (including negro spirituals), and spoken word. There are all sorts of interesting things to listen to and could be used as an educational tool. They do disclaim that “these historical recordings may contain offensive or inappropriate language”….I Bet. A few interesting ones I’ve found: (click to listen, will take you to the Library of Congress page)
Swing low, sweet chariot (1909) 
Nobody knows de trouble I’ve seen (1924)
Little David, play on yo’ harp (1909)
If you talk in your sleep, don’t mention my name (interesting…. o_O)
