Thanks for your reply. Unfortunately this is only a partial solution.
When I search for say, artist:"Ben Folds", a full list of Ben Folds' songs is returned as a list. However, when I select and play the first song-"Brick", a playlist of Ben Folds' tracks is generated that is only 20 tracks long. Ben Folds' reptoire is much larger than 20 songs. After those 20 songs have finished playing (3 of which were the same song), spotify just starts playing 'Song Radio Based on Brick'- which includes songs by many artists who are not Ben Folds.
How do I get Spotify to play the full list of songs returned by the search artist:"Ben Folds"?
