Tempo Rule Problem
Music 1 is so consistent with its song rotations because it doesn't ever ignore any of your set Clock rules. Rather, it bird-dogs problems, pointing them out for you to make the important editing choices. As a Music 1 user, you know this is smooth and efficient. But it is quite easy to set formatting rules that conflict with the reality of the library content. For example, if a station's library is 30% Female songs, the station schedules 14 songs an hour and the station has Clock rules that prevent more than 3 Female songs in an hour, then the music director will immediately encounter scheduling/editing "stops" with a bunch of Female songs backed up with no places to put them. Here's an example of that kind of thing happening with Tempo.
