I am a premium user of spotify. Since last week, I've been experiencing this problem that my "Play Queue" keeps changing after some time, without any reason. Shuffle is switched off, but still when a couple of songs from a playlist finish (in order), the play queue suddenly changes and it starts playing randomly from some other song in the playlist.
My playlist or album depends heavily on the order of the songs (because all are continuous) so this problem makes it really annoying. Any solution for it?
