I have my iPhone and iPad linked to my car. The iPad is usually the primary device but this is happened on both. If I pull up a video on Youtube, Facebook or maybe my local news station, songs that I've purchased from iTunes will start playing. Sometimes they play over the video. I purchased that music for drone videos. I don't need them any other time. I rather not delete the iTunes Store app but I will if it will fix the problem because it gets very annoying.
