Default Random music starts playing..

I'm not sure if I'm posting in the right place but I my phone keeps playing a song that I don't have in my music library every once on a while and the only way to shut it off is by muting the phone not the media volume.. and no music player nothing is opened... Some kinda adware? I'll try and get a logcat ASAP...
