I too have a Beep and have the same/similar problem. I run Spotify connect from my phone or laptop and connect to the Beep. When playing a playlist or radio station it will often repeat tracks and sometimes just get stuck playing the same couple of tracks over and over. If I try and queue tracks it is even worse. For example if I queue tracks 1, 2, 3 ,4 and 5. It will play tracks 1, 2, 1, 2, 3, 1, 2, 3, 4, 1, 2, 3, 4, 5. This seems to have been a problem ever since Spotify introduced the "Play Queue" screen showing "Current Track", "Queued Track" and "Next track". The "Queued Tracks" will list the tracks I have queued, i.e. 1, 2, 3, 4, 5. But the "Next Tracks" will list tracks 1, 2, 1, 2, 3, 1, 2, 3, 4, 1, 2, 3, 4, 5. And that is what plays. This makes queuing absolutely useless. Infact the whole "Current Track", "Queued Track" and "Next track" thing is a complete mess.
