And if you don't have testing at your disposal, give your listeners some credit. Take some chances, open the phones up and keep them interested. I know for a fact, programming a modern leaning "Hot AC" that the listeners loved it. Let's face it, when I was doing nights, people not listening to TV but calling me for artists ranging from Robbie Williams to the White Stripes to Straylight Run were definitely worth catering to. In smaller markets, you know you're doing something right when the callers are actually noticing you putting the effort into music programming and calling about those "buzz" artists. Doctor Radio is right on. Thats why when I'm in range of his station I actually turn off XM. Because I want to know "what comes next."
That feeling of excitement is gone from most stations. On most stations, I know that they're running the same rotations for three months and when they say "new music" - I've heard it somewhere else for at least a month.
My approach was simple. New releases from big names - instantly added - throw in the cool new tracks from TV and commercials - keep an eye on Fuse, VH1 when they play music. I even listen to the BBC Radio 1 UK Top 40 every week. Not every record works but if you can find one good new one a week to give some test spins to, you'll be on the edge and keep your sound fresh. This is the time when radio needs more of it.
I've been a popular morning and night jock in a market where most people ignored the radio. And that's due to in no small part, loving music as much as my audience did. What's sad is when even smaller market radio owners can't recognize the value in that position or let an advertiser scare them out of letting their PDs and MDs actually pick the hits.
