Well.....yes and no. Back in the mid 60's there was a DJ on KYA mornings named Buck Herring. Buck came to KYA from KTKT in Tucson. KTKT was a pretty tight Top-40 "Color radio" format where the jocks didn't do a lot of talking (although more than the average today I would guess). Buck's show was largely a stand-up comedy routine punctuated by lots of recorded and live humor among the records. Buck was very quick and you had to pay attention to get all the humor flying past. It was the best one-person morning show I've ever heard on radio and although he didn't play the most music he was very entertaining.
I think BigA's point is equally valid here: if you did not like the music, you would not stick around for the little humor bits between the songs. And KTKT was a station that played the Top 40 hits... mostly the favorite top songs of the moment with a couple of new songs each week.
