The Echo supports several streaming services in addition to Amazon’s Prime Music, such as Spotify, Pandora, iHeartRadio, and TuneIn. Echo Dot will have the same musical functions.
For now, Amazon is only making the Dot model available to Prime members who already have the larger Echo model. There’s no word from Amazon yet whether the device will get a broader release. But if you haven’t got Alexa in your life yet, the Internet is full of tips for finding ways to work around that restriction and pre-order the Dot. The device costs $89.
