Anybody work in commercial radio that can answer me this??

[hopelessbusiness]

I listen to commercial radio at work, and I'm wondering why, despite the raft of back catalogue and current music that must be at their disposal, they play the same songs over and over? If I made a bingo card with, say, 20 songs on it, I'd be able to tick them off every day!
Doesn't seem to matter which station we listen to, they all have their staple tracks.
Drives me cuckoo!

they have an A and B playlist yes. and a current list of “no” songs too. it’s a family member who’s the presenter and has told me. you can just make a playlist and listen to it on your streaming service?

It's a radio at work so I have no control over it!
Just have to hide in the toilet when Stick Season by Noah Kahan comes on (again...!)
