Google Home Smart Speakers can now play music from the free, ad-supported level of YouTube Music. To play YouTube music on your Google Assistant intelligent speaker, you'll need to subscribe to Google's paid YouTube Music Premium service for $ 9.99 a month. The new service is now available for Google Assistant's Google Home and other intelligent speakers in 16 countries, including the US, UK and Australia.
Unfortunately, the free tier does not allow you to request specific songs from the Smart Speaker. Instead, it's meant for playlists like Latin Vibes. When we asked Google to play Creep from Radiohead, our intelligent speaker played a related Nirvana song rather than the desired Radiohead title. … after playing an ad for YouTube Music Premium.
You can set the default streaming music service that your smart speaker uses by going to the "Music" section under "Music" in the Google Home app's Settings menu. From there you can select YouTube Music as the default music service.
None of the layers in YouTube Music are currently supported by smart speakers using Amazon's competing Alexa language assistant.
Playing music from a smart speaker eliminates one of the biggest frustrations of using YouTube Musics free tier. The app does not support playing music in the background. If you're not paying for the premium level, you'll need to keep your phone screen on and leave the YouTube Music app open to keep your music running. Without screen or multitasking, the intelligent speaker has no such problems.
