Full playlist not downloading on Spotify

[webtronix77]

Hi, I have tried several playlists and not all tracks are being downloaded - some show with an error as pasted below, which I assume may already be logged automatically and sent over to your logs server.
Any ideas as some tracks download perfectly.

below is a playlist where 'naina' is not downloading correctly as is corrupted with only 84kb size, but ins same playlist, 'hosh' downloads perfectly with no error
