YouTube Music update finally brings one of the most requested features
However, with Android Auto support, you can now tap on the music tab and choose YouTube Music as your music source. Then, you'll have five options that you can choose from Mixtape, Recommended, Last played, and Downloads.
Unfortunately, as AndroidPolice points out, YouTube Music doesn't offer great curated playlists as other music streaming apps like Google Play Music and Spotify. The best you'll get is some auto-generated playlists based on your favorite songs, as well as some standard lists the include some of the most popular music genres.
If you didn't jump on the YouTube Music bandwagon yet due to the lack of Android Auto support, now would be a good time to reconsider your music streaming options while driving.
