They were playing stuff on there yesterday at around 11:30 AM. When I first listened in, they played a 90s "Always Coca-Cola" ad followed by a 50s Delta Airlines jingle, then went into playing a few 70s and 80s songs. It turned out to just be them testing out their Virtual Jukebox system. This happened until right around, if not, noon sharp.
On another note, 103.5 also went off the air at noon, only to return again that evening.
