Well, I am glad someone brought this topic up because although I don't really listen to radio during the week (other than 89.5 or 95.5 overnights), I did notice the music in the mornings on KZZP for quite some time now, but just didn't feel like coming to say anything about it. It will make me listen to KZZP more often because since I am a radio AND music fan, I hate going to sleep at night, knowing that if I should wake up to toss and turn a bit in the early morning I'd have to change the station if I want to hear some music until I fall back to sleep. That used to keep me from putting it on KZZP overnights for a few years. I'm glad that KZZP started doing music in the mornings, and I'm glad that KZON was successful in their ratings with their more music mornings. I assumed that if KZON maintained high(er) success while still doing more music mornings, then eventually other stations that weren't already doing this would be inspired to or get the idea to also start doing so.
I do have to say that as of right now, my top 2 mainstream stations on the top 40/rhythmic side are KZZP and KZON. Most people may not notice or be aware, but KKFR has changed within the past 3 to 4 weeks. I don't blame them for keeping it all extremely safe and predictable every single day of the week, but for people like me, I very easily and quickly get bored when specialty shows are changed up or removed, especially if the regular format isn't exciting enough without those specialty shows.
I can't really say much more since I only listen to radio on Friday and Saturday nights, so I may be missing out on quite a few things, but I will say that for me personally, Power's best days (in regards to the most recent times/past two years) in sound were spring 2009-January 2010. Now, I'm with KZON all the way. As a matter of fact, KZON (along with KZZP to some extent) seems to be getting better in some ways, with all this being due to the latest trends in the rhythmic / instrumental sound of top 40 & rhythmic music... . ..or maybe it's just now that I haven't been tuning into radio as much, things seem to sound fresher and newer the times I do tune in. I have to give KZON kudos for the dj's they are bringing over to the station. Hopefully they do get more airtime, and hopefully it will be rather sooner than later.
