If you're a YouTube Music user and have a smartwatch running the latest Wear OS 2 version, you can finally listen to YouTube Music on the wearable. It's possible to stream over LTE or Wi-Fi without your smartphone. You can download songs to it to listen to while offline, control playback, manage downloads, and like songs all from your wrist. The YouTube Music tile will act like a quick-launch remote for recently played playlists, and you can also browse the main page of the app.
If you're a premium subscriber, you won't have to endure ads and get access to that download function. It will also start aggregating new playlists based on your listening history.
