Oddio Overplay is predominantly a catalog of neat-o websites that offer legal and free sharing of music. It began in 1994 as the music division of the now defunct "Boxy", in the years since, it has lived in various locations with various faces.
The primary purpose of this site is to connect artists and audiences. Artists who want the world to hear their music offer it online for free. Oddio also refers visitors to music archives, such as the United States Library of Congress, Opsound, free netlabels and the Internet Archive, that are using the Internet to allow the public to access their sound resources.
