With the exception of my local love for KACC, I have been listening to K-Hits, nearly exclusively, since late winter and I LOVE it! Kudos to Kevin Charles and the rest of the staff there; you're really giving the listeners what they want. Black Sabbath would be sweet!
As far as The Arrow needing competition, it wouldn't be difficult for anyone to exceed them, these days, in my opinion. Clear Channel's whole cluster of stations is becoming more and more cookie-cutter natured, daily (In my view, they're stale, cluster-wide).
There are many establishments in my area that have switched from Sunny to K-Hits during normal business hours. I never thought I'd see the day, but I'm glad. The variety of music on K-Hits is more appealing to me and apparently, based on the vast number of businesses bolting from Sunny in my area, I'm not alone!
That being said, I've always been a believer that fans of classic hits will listen to a station that plays classic hits, as opposed to a station, like Sunny, which tries to play a blend of today's music, with some classic rock and disco mixed into the playlist. Sometimes, trends don't tell the tale of the most important thing --- giving the listeners what they want.
Again, thank you Kevin C. Keep rockin' man; I'm loving it!
