YouTube Music announces its streaming app and lays out its features. Although the app has video, of course, it's also "made for listening" with official audio, offline listening, background listening and ad-free options. That way, you can stream artists like Ariana Grande, Dua Lipa and Alan Walker. YouTube Music also shows off its playlists that can fit your mood as well as its smart search feature, which allows the use of emojis. Customers are offered one month of YouTube Music free.
