FWIW, every bar I know of around here has a jukebox. Nightclubs, that's another matter, although, some do. I also know of some private clubs with jukeboxes.
If it were up to me, I prefer to have NO music during a break, so, that people can talk. But I've had club owners tell me they want to play the jukebox because it's revenue. And I'm thinking, my gosh, what are we talking about, five dollars? How 'bout just NO SOUND during breaks.
Then again, I understand how you could lose some patrons during a break. That's another reason for NOT breaking unless you have to. Of course, the standard of every band I have ever seen around here is 45/15. But I have seen some Texas music acts play for hours with no break.
Also, other than a large nightclub, I am not aware of any place around here where 250-300 people regularly gather to hear music except for a concert. I'm serious. It would be rare, anyway. You east coast guys have LOTS of people!
