I was wondering if this should be a bug report or a suggestion, but sice the game actively prevents and tells you about this, I think its a feature, not a bug.
Why cant we place boomboxes inside to pump music? It would be cool to organize parties and other stuff.
Placing boomboxes inside houses
Will be enabled inside properties next update. Thanks for the feedback. I agree that's one of the main uses of it for a house party!
After the next update... Can we place that in bank??
