It's pretty surprising that Google is updating the YouTube Music app instead of scrapping it wholesale. Before the most recent update it mainly served as a way to cast tunes that don't exist on the Google Play Music app to a Chromecast Audio. With the new patch, though, it's getting a little more useful. Now you can download albums, playlists and individual songs to your mobile device instead of a random mixtape based on your listening history. Pretty cool, right? Time to stock up on some obscure remixes for this weekend's camping trip before you leave WiFi behind.
