My Question or Issue

See attached screenshot. Note the default Android icon with a small Spotify logo next to it, with the song "Everybody Walkin' This Land" next to it. This song was recently playing on my Spotify. Touching this icon leads to a toast that says "App isn't installed". Attempting to drag the icon onto the home screen leads to no message, but the icon does not appear on the home screen. Attempting to uninstall the icon leads to the message "This is a system app and can't be uninstalled".

Closing the app's page does not make the icon disappear. Restarting the phone does make the icon disappear. 

Cannot repro the issue. Have forced the same popup to occur, but it works with different/same songs. Appears to be highly intemitent. 

Unfortunately, I cannot submit a Android bug report, logcat, system dump, or apps as my phone contains confidential information.
