>do listeners only want to hear the most popular songs?

i think most listeners only want to hear those most popular songs.

here in Chicago we used to have Herb Kent spin R&B oldies ('dusties') on Sunday afternoons. great DJ - he'd often play deep cuts from legendary catalogs. and one-hit wonders who'd been left off playlists from other oldies stations. but he also played the oldie hits too. i dunno if he's still on b/c i don't listen to radio. but i got much of my R&B history education from listening to his show in the 90s. it's awesome. i think he's still at it.
