Spotify, Apple Music, Google Play, Tidal and Amazon Prime Music began streaming 224 Beatles tracks [bbc.com] on December 24. Other services that have secured the band's catalogue include Deezer, Microsoft Groove, Napster and Slacker Radio. The Beatles as a corporate entity have been notoriously slow in adapting to new technology. They waited five years to issue their albums on CD, and didn't talk about the download Revolution until 2010 - seven years after the iTunes store launched.
