The only way to save Spotify? Five reasons why Spotify should go subscription only

f I had a quid for every person who has told me recently that they are about to subscribe to the service but just haven't quite got round to it the beers would be on me. If Spotify canned the free service then those users would have no choice. If the service was £5 a month the subscribers would base would be huge. The target is apparently to convert 7% of Spotify users into subscribers. Spotify hasn't released figures but I guess the figure is a long way off at the moment, even after all the innovation. This way round I think 15% would be feasible.
