Dixie Broadcasting is an online radio station. You need to download the small player application from their site. It plays, obviously, Confederate music and some Union-Confederate neutral old American tunes. I very much enjoy listening to it. Go to the link below and look for "Southern Music Heard on Dixie Broadcasting". There will be links to various musicians' websites and most of them let you select mp3 files to listen to if you don't want to depend on Dixie Broadcasting to select what you hear.
Lately it seems their music selection is a little better during the day because at night they broadcast more lectures, which I don't especially appreciate.
