Amazon's Echo speakers have been gradually improving in quality, and it looks like Tidal wants to seize on that opportunity. The streaming service is now available on all Echo devices in the US through a dedicated Tidal skill. Link your account and you can play that Beyoncé or Jay-Z exclusive with a quick voice command. You can set it as your default music option if you'd like, but you can always add "on Tidal" to a command if the service remains secondary.
