Every station really wants that. The more you rely on the station the more loyal you become.
With a network like K-Love, knowing that it airs a Christian pop format, if I saw an ad like that, I'd probably be inclined to feel as
@bmasters1981 does to an extent.
While I'm neither autistic nor literal minded, I do see his point that subliminally, that kind of ad campaign almost implies that they regard only the music they play as "good," and it's a sin to listen to anything else (the "law" in bmaster's "K-LAW"). This goes beyond most secular stations who only want to play the music their audience wants to hear (based on charts and ratings research, among other things) because for them, more listeners = higher ratings = more ad revenue.
K-Love, on the other hand, while they, too, need to make money, they're based on a noncommercial, donation-supported model, so they're probably a bit less concerned with whether or not their audience like the music per se than with the overall message they're getting out (granted, K-Love is probably on the milder side compared to, say, Relevant or VCY).
However, I must clarify that I may only be feeling this as a result of my bias against Christian radio in general, so take from my opinion what you will, with an appropriately large pinch of salt.
