Samsung Galaxy Watch 4 & Watch 4 Classic were the first watches to get YouTube Music app. At that time, Google hadn’t revealed when it will release an app for other Wear OS watches. Later, it announces to release of the app for other Wear OS watches, which are powered by Snapdragon Wear 4100/4100+ chipsets. Now, as the company mentioned, the music streaming app is available for Wear OS 2.0 running smartwatches. The older watches from Fossil, Oppo, Suunto, and Mobvoi can download the app from the Play Store for Wear OS.
The music streaming app delivers all the latest songs to your smartwatch. Users can search for any songs or find them from the recommended song list. It also gives you the option to download the songs on the watch to listen to them later in offline mode. Though it has a download option, it is only available for premium users.
If you are not a premium user, then you have very limited options like the Spotify music streaming app. It also requires connecting your phone-running YouTube account to get all the features.
In a Play Store listing, it mentions the app supports Moto 360 & TAG Heuer. Both watches come with Qualcomm Snapdragon Wear 3100 chipsets. Previously, the app was launched for watches built with Qualcomm Snapdragon Wear 4100 & 4100+ processors.
The update has rolled out in all the major countries, and you can download it from Play Store. If you are not seeing it yet, then wait a while to come to your device.
