I like using the "The Upload" feature on the Discover page, and use it to create a new (private) playlist to listen to every day. My understanding is that the playlist created will be stable, but that doesn't appear to be the case.
Sometimes the playlist will update itself in the middle of listening to a track. The track that I am listening to will stop playing in the middle of the song and be replaced by another track that starts playing immediately.
Is this behavior intentional? Is there a way to stabalize the playlist for a certain day?
