Jazz isn't hard to find on the radio because of payola. Jazz is hard to find because stations that play a lot of jazz attract fewer listeners than stations that play a lot of pop. Period.
It's not surprising to me that music that's more complex intellectually and emotionally has a smaller audience. It's surprising that so many musicians who should know better think that putting their brilliant, emotionally and/or intellectually complex music in front of a larger audience will make it more popular than the Bay City Rollers. Again, this isn't about what sucks and what sings.
