On OSX Mountain Lion I was playing a song I found through the search feature. I ctrl+clicked an empty playlist and selected "Choose as current playlist".
I expect the rest of my song to play and the rest of the search results to be removed from the upcoming play queue. This all happens as planned, however, an unusual error message appears.
"This track is not available. If you have the file on your computer you can import it."
This doesn't interrupt my listening experience but the error message implies a problem that doesn't exist. The Error message goes away when I select another track to play. The bug seems to be aesthetic only as there is nothing abnormal I can do with the error message.
No error message when attempting to choose empty playlist as current playlist
Create a new playlist, leave the default name and press enter, ctrl-click (right-click) the newly created playlist and select "Choose as Current Playlist"
Add menu item: Playback -> Advanced -> Pause/Stop after current song
Using a playlist to collate tracks (podcasts, long running live tracks), want playback to stop after current track, using workaround in lieu of complicating functionality
