"Unable to Play Track" in Shuffle Play Kills the Music

[JesusFreak]

I am ShufflePlaying the EP "Remédio pro Veneno" by Rogé, and it consistently has the nasty "Unable to Play Track" pop up.  That kills the music.  No way to continue.  Restarting  works for a while until the message pops up again.  Very bad.

Strange, does it always happen on the same track?

[JesusFreak]

Hard to tell exactly as Spotify includes other tracks from the same artist and the pop-up does not specify the track.  It's around the same time after starting shuffle play.
