I think the point to be made here is that KRTH has been a beloved station for many years. Their consistency in music, the legendary air personalities, the imaging and such gave them a distinctive sound. As the pros on this board have noted on many occasions there was what they determined was a business need to evolve from oldies to what their definition of classic rock is. That it's all taken place in about a years time, without officially announcing a format change*has been difficult for many of the long time listeners.
Perhaps format change is too strong a term, but most listeners would not recognize this brand of KRTH and what's taken place since jhani left in 2013. Not just the move into the 80s and elimination of the 60s and early 70s, but the change from the soft rock of Carole king, Jim Croce, James Taylor and bread to a playlist that now has a much harder edge and includes guns and roses, ac dc, depeche mode. That, and the move from a KHJ style of music to much more of a KLOS format is to me the bigger change. Other stations that consider themselves to fall under that "classic rock" umbrella have radically different playlists. Take a look at what WOGL played this weekend for example. Very little similarity between what they're playing and where KRTH has positioned itself.
Was this weekend the final turn of the ship? It will be interesting to see what KRTHs playlist will look like beginning tomorrow. With CVD gone, or in a reduced role, indications are the station will continue their evolution and begs the question, how much longer will the likes of Charlie tuna, Jim Carson and the shotgun remain? From strictly a non professional, listener only viewpoint, they, like the heritage jingles don't appear to fit any longer.
