Hi David and Matt,
There are around 6,500 songs in the CORE category. Most of them have a Style or multiple styles associated, which is what is forced in the clock, "CORE and style of 50s, 60's, 70's etc".
I've noticed however, there's a new option on the Show Rules page, where Styles are currently all showing '0'. This seems new, does this override anything forced in the clock perhaps?
