Lucky for me, I figured it out myself, but it a someone else problem. He somehow managed to unintentionally buy music from iTunes, and ever since then, every time he put his phone down.... he somehow managed to hit the play\pause button on the white cord of his ear buds. The user thought it was magic, because, like many other iPhone users, they don't know what the devices are capable of. He keeps the white ear buds plugged in all the time (that was my first hint.
The most aggravating thing to him and me, was that you can't disassociate the music from playing! You can't go to settings and turn that functionality off! PLEASE APPLE.... PLEASE stop forcing "features" onto all of us without a back-out option!!!!!
The purchased songs were not even downloaded, they were on the cloud. Found a way to delete the "play list" and it stopped happening. Just like the battery\performance slowdown "feature" to save your battery life! They should but an option under settings\battery "to turn "performance throttling" off
But that wont force you to buy new batteries or new phones from them now, will it?
Hope I helped a Smidge.
