In this context, "good" means "listeners like it" and, simultaneously, "few or no listeners dislike it".Whats “good music”? Respectfully, that kind of seems opinion based, does it not? That’s like me saying, with many chr stations down, they should make “better music”. But, those artists in many cases are well decorated with awards. So who am I to say they should make “good music”
"Good" is defined by a station's listening base. It does not really matter what the PD or MD thinks.
