My Question or Issue

When I listen to a play list or Music made for me, it will stop the song im listening too and play a randon song that is not on the list. But when I try to turn off the song or change the song it, it keeps playing the song  and wont let me play another song. I have to shut done spotify or restart my iPhone. It just started doing this about 6 weeks ago and keeps happening more often. 

PLEASE HELP ME, ITS REALLY REALLY ANNOYING AND I DONT WANT TO PAY FOR SOMETHING THAT DOES NOT WORK.
