After a six-month beta period in the US, Sonos has integrated Amazon's Prime Music service into its Sonos Controller app in Europe. That means if you're a Prime subscriber in the UK or Germany, you can now access and stream Amazon's library through the Sonos speakers in your home. It joins Spotify, Apple Music and a mixture of other streaming services that have already partnered with the high-end speaker brand. Amazon will be hoping its own integration can be the tipping point that gets Prime subscribers to ditch its rivals and rely solely on its own music streaming chops.
