Playing random songs???

[emily_daniels54]

I do not have premium. I will be shuffle playing a playlist (with more than 15 songs) and out of nowhere, it plays a random song I used to listen to years ago (maybe something from an old playlist?). This happens in the middle of the playlist, not at the end when they "recommend" songs. It gets annoying when you're trying to fall asleep to some rain noises and then Pitbull comes on. Help?
