Unable to Update Playlists

[billyboy01253]

I have just installed Spotify on my HTC One. I have a premium account so I downloaded my Playlists and switched my account to play offline. The problem is that when I add tracks to my playlists they do not download into my playlist on my HTC One. I have not exceeded the number of tracks that I can download

The only thing that I notice when I connect the USB cable from my Laptop to my HTC One, I get a message that the drivers has not been installed successfully; the reason being that the MTP device is unplugged. Can anyone help.

You don't use a USB cable. Have a read of the guides,
