YouTube Music is still catching up on features, and this time around it's one of the most important elements: the Now Playing screen you see whenever you listen. After weeks of testing, the Android version's updated playback screen includes clearer and more persistent buttons, including Up Next (to show your queue), shuffle, repeat and flipping between pure music and videos. However, it also includes an "experiment" that displays lyrics -- not a new feature in music apps, but appreciated all the same. Just be aware that it only works with some songs.
