1. The short playlist of WJZZ was instrumental in their recent demise, as well as "Smooth Jazz" stations nationwide. This was one case where the L.C.D., national programming, came back and bit them. When even the girls at the dentist office complain of hearing "the same songs over & over", you've got to know trouble is brewing. Even some of their top DJs chimed in as to this being the reason....
2. When I was growing up Top 40 while concentrating on hits, to some extent, was at least a very diverse blend of genres. Everything from Motown, to rock, pop, even some comedy, jazz, & movie themes. Then when FM hit, the "Underground" music stations also played a very eclectic blend of styles & genres, you'd hear Hendrix & Cream, then "Walk on By" by Isaac Hayes, CTA (early Chicago), then some BB King, & Joni Mitchell.....
So obviously, listeners used to be very broad in their tastes. I think it's radio & programming that channeled and separated genres, to the point that now, kids up to young adults expect that to be the norm..... unfortunately.
Today, those fed up with the same 30 songs all day, have moved to cable radio, internet, or their own mp3 playlists. Which is also a reason why talk radio has become so popular. I'm a musician, but if I have to listen to radio, I'd rather hear talk, than repetitive (& usually crappy) music & inane DJ prater.
3. WAOK now only has two local hosts 6-10am, and 4-7pm, the others (Al Sharpton, Warren Ballantine, Bev Smith) are all national. They are popular, but the station's weak signal, and even weaker marketing (despite being "sister station" to WVEE), keeps their numbers so low.
I think there's definitely a market here for "less conservative" talk radio, as long as the hosts are entertaining, and not simply ranting mirror-opposites of Rush/Sean. It gets really tiring hearing the very same talking points everywhere you turn. I don't know why no one's come up with an entertaining duo with varied perspectives, oh wait, there's the Frank & Joe Show, but that's only two hours a week....
