When I skip songs sometimes a song with the canvas moving album art comes up. if I skip that before it has a chance to load the moving image it will start a new audio stream and play that song. I can then continue using the program as normal and play music va the original stream but now there is a 2nd stream. its shown in the volume mixer as just 'Spotify'. The 2nd stream cannot be controlled and will play from start to finish before stopping and killing the 2nd stream returning the program to normal. closing the program will also kill the stream. This is a fresh OS install.
