Huey Morgan has a go at Lauren Laverne on Twitter, implying that while he "builds" his programme by hand, she gets hers handed to her. I love it when deejays have cat fights. In public they're always fulsome in their praise and respect for each other. In private they're absolute bitches about each other and the most popular gibe has always been "they get handed a box of records and a running order by their producer". Now that most radio stations are controlled by a hard drive many don't even have to open a box any more.
But does it matter whether DJs choose their own music? Not from the point of view of "credibility", whatever that is. Most of them have advertised tastes which are very orthodox. In my experience the DJs who make a song and dance about their passion for music are often more bogus than the people who just turn up and do a job. But it matters if you think DJs should be playing records that they feel like hearing at the time they feel like hearing them, that they want to put you in the same moment that they're in. Which I suppose I do.
