There's a guy in our bike club that always rides with music playing via a bluetooth speaker mounted on his handlebars.

I understand where he's coming from - when I ride indoor, I always have music going. I'd understand playing music while riding solo outside, even though I don't do it. I'm mostly okay with his playlist, too.

But to play music while riding with a bunch of other people? Are they not interesting enough for him? It's hard enough to hear each other if we want to chat without music playing. And if someone calls out a safety item (car back, hole, debris, etc.) he and others near him are less likely to hear the call, so there's a potential effect on safety as well.

Fortunately, I've gotten fast enough that he's never in my ride group any more.
