Has any one been able to get anything but classical out of the speakers in the community objects? do you have to match them with a regular stereo? all the speakers play classical. How can we have a dance club with classical? Can anyone clue me in? Thank you in advance.

I had been asking this as well. I made a dive bar and when my sim wen there is was classical o.O

They said by crtl+shift and click would give you options to change the music type. Though I found you can only do this while in build mode at the place.. not while in play.
Also I am pretty sure you need to have testingcheats enabled first.
