Interestingly the last time a station did well in Soft AC was when KOST-FM Los Angeles had Dick Clark do TV promo's for that station.
Note as of 2016 KOST is MainStream AC for Iheart Radio. I'm not sure how Soft AC is going to work in 2016.
KIFM in San Diego is a softer more traditional AC and the latest 6+d has it #1, and despite the music skew, is now in the top 10 in 25-54.
Similar things have happened with WFEZ in Miami and the adjusted WDUV in Tampa.
