I'm sure you're not the only one, but if you're not in the majority, it's not going to matter. The key to winning in the ratings is to do what works for the biggest block of listeners within the target demographic. As we've said before, slowing down the rotation means the typical listener may not feel she/he is hearing their favorite songs often enough, given that they're at most usually hearing them only once every three weeks or longer.
So........if you were programming a classic hits station today or in 1985, would you have weekend specialties or not (true to the bone though, not fake specials) to lessen the weekday monotony. How many core songs would you carry overall and how often would you play these core songs?
