Background Crash iOS

[EricRit]

Hello, I have an iPhone 5s and I have used Spotify for a couple years and have been using premium for about a year. I have had no problems with the app until today. I open spotify and play a song then turn off my phone. After about 30 seconds the music stops playing and when I reopen the app, Spotify reloads and goes back to normal until put in the background. I love Spotify and would love if someone had a fix to this issue.
