I still work in radio and have for more than 30 years. Perhaps I'm an outlier, but I never cared about the DJs, never felt a connection, never wanted their Morning Zoos or their Tammy and Frankie in the Morning junk, with the fake callers, the forced laughs, the crappy contests, the gossip lifted from other uncredited sources. All I ever wanted was lots of unrepeated music. Or, failing that, lots of intelligent talk and news.
You might get all-music at night. But in the mornings radio listeners want to hear talking.
I don't want to hear morning show hijinx. I will gladly listen to well-produced news and features.
