Library of Congress releases free 10,000 song database.

The Library of Congress launched a sort of "jukebox" which is actually a free database of over 10,000 songs recorded before 1925.  While I haven't had a chance to scour any of it myself, the dudes over at Altered Zones have and have made a little playlist of choice tracks.  Pretty cool idea if you ask me!  I'll be searching it myself...
