If, like me, you signed up for a free year of Spotify Premium through Virgin Media you'll find that if you want to continue with the service you now need to pay. £9.99 a month to continue the Premium service, £4.99 for the Unlimited (no ads, but no mobile option either) or you can stick with the free service with those pesky ads every few tracks. Details at Spotify.
Which is fair enough - the original offer was last August so I have had a couple of weeks' extra at no cost. Somewhat surprised that neither VM nor Spotify emailed me about it, but the whole thing's been pretty half-hearted by Virgin Media from the start. And there are still occasional issues with the service streaming over the VM network, especially for Sonos users.
