In the 1980s-90s, many Los Angeles department stores and doctor/dentist offices had KOST playing. Like most AC stations, KOST now plays Billie Jean, Straight Up, Make Me Smile, Harden My Heart, Girls Just Want To Have Fun and many other songs that never made the AC charts. Their slogan is "Southern California's Favorite Soft Rock." I foresee the day when the phrase "adult contemporary" will no longer be used. As for all those stores and offices, most of them now play satellite-fed classic rock. Some of the larger chains, such as RiteAid, have their own in-house music service which provides a mix of oldies and classic rock. I invite all of you to come here and visit the huge Glendale Galleria shopping complex. Don't enter any of the stores---just walk through the mall. No matter where you walk, you'll hear at least ten different rock stations blaring from the various stores. It's cacophonous and it's deafening...which is why I no longer shop at the Galleria.
