Yes: you need to be more specific with the question. “Any ideas” about what? 

And, to help us a bit more: how is your system set up? What speakers did you have grouped? 

Hi, I have an Arc, 2x 300’s and a sub in the living room and 2 x 5’s in the bedroom.  Wife was downstairs watching tv and when I played music on the five’s it turned the living room group off.

what am I doing wrong?

As for groups, the living room has arc,300’s and a sub

bedroom has 2x 5’s

sitting room has 2 x 1sl’s and a sub mini

 Stay off the grouping screen.  Use this screen to choose your 5s then select your music.

Were any rooms grouped and playing from tv? What was your source for playing music in the drum room?

No groups added, Tv was playing a movie, via virgin tv, I then selected drum room to play music from my Amazon music via the iphone

And Mopac, how do I get to your above screen shot? 

 This is on an iPhone.  On the Home Screen swipe up from Now Playing at the bottom of the screen.
