A while back I posted the addition of the subscription-based MOG service to Sonos. In this last week the similar service Spotify has been accessible in the US and added to Sonos. Now you can stream 15 million tracks to any of your Sonos devices starting at $4.99…In addition, Sonos has added a new listening device to their lineup. Now you can get the Sonos Play:3 for only $299!
