Ive had music from an outside source just start playing out of the blue through my home speakers randomly.  Explicit rap, in another language mixed with english at 3am.  And then again in some sort of turkish/eastern european music playing during a show I was watching.  Both times I couldn't turn it off with the app or with remote.  I had to unplug the speakers.  I don't know if someone has hacked my account or my wifi.  But I've changed passwords for both.  Its happened 2 times since.  Same types of music or similar.  Not trying to profile the type, just keeping to the issue really.  Just odd.
