I don't really like the idea of battle of the jams, or doing a new song vote because since many people have been trained to be close minded, if anything sounds "different" or "odd" in any way, people will call / vote in against it. I remember it happened, for example, with Craig David "fill me in" and Khandi "don't think I'm not" because people could not handle the fact that the beat tempo changed or that it was something different for once. What happened as a result, the station didn't play those songs, they blew up, and all the other stations played it instead. People tried to complain about "gotta get through this" at first on one of the two example stations I was talking about, but fortunately they weren't voting on it, but just started playing that one as new music.
What's funny is that after everyone else thought those songs were "cool", then people started requesting and wondering why the station wouldn't play it.
I do have to admit that I do love those stations that tend to deliver the most new hits during a time period, and here in Az, I believe it's KZZP. I also love stations that do the overnight new music play, which our KZON does, but sometimes wish they'd be a bit newer during the day as well. KKFR seems to be on top of things as well. Many times, the new music is just added in, so it pretty much stays fresh. Our rhythmic / rhythmic top 40's in Az. do a pretty good job and although not perfect to my tastes, I'm still happy with what we have so far.
