So, I'm premium. I read about the AutoPlay, but is not about that. After playing a few songs of a group/album/list/radio, Spotify starts to play a song (it's not the same song, but it's always playing a song) and with no volume. That means that I can see how the song is finishing but I'm not listening to it, and then starting to play it again.
I collected more information about the issue. All the songs played seems to be from the same list or radio, but I'm not sure.
It happens with the software in Windows and it happens in my Amazon FireStick. I haven't prove it yet on my phone or my PS4.
It's quite annoying since none of the lists produced are going to be accurate at all and I use to play the songs that I listen the most for a long time and, since I sleep with lists on, and wake up with the same issue, all the historical data is corrupted.
