I don't suppose this counts as a 'moment', stictly speaking; more of an 'app' of the year, but I can't help but mention Spotify (again).
It's just a great, great way to access and listen to music. It's been a treat to be able to hear long-forgotten favourites, discover new ones and just generally have a ball. Music to suit any taste and every occasion.
All they need to do now is get the full Yoko Ono back catalogue on there & it's 'job done'.
