James' observation brings up a point which should be -- but isn't --kept in mind when talking about stations with "heritage" formats.
James, if I recall, is in his 20s. (Please correct me if I'm not recalling correctly.) For him KOST has always been an AC, which goes back to 1982. He could be in his 30s and still have that perception.
Flipper is a bit older and would remember both formats well. To me, all of the BM/EZ stations -- KOST, KJOI, KXTZ, KWST -- sounded more or less the same, but his observation did jog my memory of the harps.
Michael and I are very close in age, so our radio listening habits go back to the 1960s, and would have included KADS for me as well, except that I only had access to AM radios until the early 1970s.
If any of us were around when 103.5 first went on the air, it would be remembered as "good music" KGLA before McLendon launched KADS.
Kind of adds another perspective to discussions about stations moving up the timeline with their on-air music libraries to stay in the upper adult ad buy demos.
