Sorry to hear that you're having such an experience with the app.
We'd recommend running a clean reinstall of the app. Please follow the steps from this Spotify Guide exactly, as this will assure that all app data is cleared completely, before reinstalling.
Also, make sure that Battery Saver mode is not switched on.
Keep us posted on how you get on with this.
