Google Home will now work with the free ad supported tier of Spotify
At Google I/O in May, it was announced that certain streaming music apps would gain Google Home support
The Amazon Echo gets much of the attention when we talk about smart speakers, which is no surprise given its 70% market share. In second place with a market share that exceeds 20% is the Google Home. While the Echo is powered by Alexa, the surprise breakout star of 2017, Google Assistant is found on the Google Home. These market share figures are bound to change when Microsoft's Invoke and Apple's HomePod are launched later this year.
Earlier this month, Google Home added support for another streaming music site called Deezer, and we also expect the product to add SoundCloud to the list of streamers that it is integrated with. If you want the first chance to use new features that are being added to Google Home, you can now sign up for the Google Home Preview Program. This will allow you to test out new software updates and features added to the smart speaker before the vast majority of users get to experience them. To sign up or to see more information about the preview program, click on this link.
