Won't play anything in my playlist

[Bearzo124]

I listen to Spotify when I go to sleep at night. I have a playlist of 500+ songs that are all from different video game and movie soundtracks that are nice and calming and don't have lyrics.

Up until just now, I've never had an issue. I deal with an annoying ad every once in a while, but whatever. So I open up my playlist as I'm getting into bed this evening, and it starts playing nothing but Dafe Punk, Laty Perry, and Lorde. I don't want to listen to this garbage, and nothing in my listening history suggests that I would EVER want to listen to this.

I have the free version of Spotify, and I'm using the latest update (Aug, 28) of the app on my iOS device. I really just want to listen to my nice lyricless music, and not pop trash.

Thanks for any help
