At one time, there was a post on the forum that discussed how to change the music selection of the wall speakers at clubs. I, however, have been unable to find it. So, if anyone could please tell me, I'd be ever so appreciative.

I think you have to go into Buy Mode on the lot and then it's either shift+click or ctrl+shift+click on the speaker and you get up the pie menus with different options.

Thank you so much, I couldn't remember which buttons to use.
