The KLOS playlist is a little too all over the board for its own good. They need to exercise moderation on the deep cuts and the 90s alt product (Weezer, as an example) and play more classic rock hits.
If they tighten the playlist, the complaint will be that it's too limited, too repetitive, and too boring. The porridge is always either too cold or too hot for the audience. But yes, if they tighten the play list, it will likely result in higher share. It's a similar issue at WBOS in Boston. The one thing I note is that the addition of Kevin Ryder to the staff hasn't helped the ratings.
