My Question or Issue

 I have the option to turn off Autoplay under the Playback settings. However, even when I turn it off, it will still start playing similar songs. On top of that, it doesn't even let the playlist finish. I tested this by making a playlist with only one song, and when I tried to play it, it didn't even play the song in the playlist.
