Wish I could offer something specific but after 20 minutes I'm only hearing occasional very faint music, sounds like guitar rock/blues when it peaks above the mud. It's 1323z now and probably will fade completely soon here.
1341z: Possible ID, sounded like "Radio Gagggaaaaa" sorta growled-drawled out.
