Songs keep playing from queue!?

[sulinaaa]

I know this has been brought up before, but I still don't know how to fix it. So I choose a playlist/radio I want to listen to, the first song plays and I'm happy. But then it starts playing these random songs from the queue! It's really irritating when you're in a certain mood to listen to a certain kind of music, but random **bleep** keeps playing. Everything was fine until today. Someone help please!
