I used to work in the back room of a Target and the stereo was always tuned to the same radio station. They just played 12 songs, in a loop, 24/7. I always knew which song would come on next before it did. I think most radio stations are like that- they just have a loop of about an hour of music that they play, and most people aren't in the car long enough to figure out it's just the same songs over and over.
Hm, no I don't remember the frequency but they would do the standard thing where the announcer would come on and say "This is WSUK 99.7 playing the biggest hits!" and so on.
