What music is supported using Alexa Voice Services?

Currently, you can use Alexa to initiate streams from the following services:

And Coming Soon:

While many of these services have crossover with Play-Fi, when a stream is started using Alexa Voice Services, it specifically comes from Amazon’s platform rather than from Play-Fi or any other protocol. Though you can't yet start a DTS Play-Fi stream, you can still use voice commands to control a currently playing product that was started from Play-Fi, Spotify, etc.

In addition to the above, more services are being added all the time. To manage and sign into these services with your Amazon account, use the Alexa app.
