The YouTube Music app organizes all the different versions of your music into a central hub, with guided paths for artist discovery and song curation that make your experience a real listening adventure.
For convenience, you can adjust settings that tell the app your preference for video or audio (or both), how much local storage you want to allocate to offline access, whether or not you want to save over Wi-Fi, and the resolution quality of the videos.
Much of the app is designed to bring the user into a "lean back" listening experience where YouTube curates a playlist for you to enjoy based on your individual music taste.
There's a separate section of the app called YouTube Music Today that organizes playlists into thematic silos according to genre, popular music, internationally trending songs and albums, eye-grabbing videos and more.
You can even control how much variety you'll hear for any given station, similar to Pandora: there's a slider inside the app settings for this purpose -- if you position it all the way to the left, you'll hear less variety (meaning only the original artist's work will play). Drag it all the way to the right and you'll open yourself up to more variety with live performances, fan videos, lyric videos, tributes, related tracks and more.
When you download the YouTube Music app, you'll automatically get a two-week free membership to YouTube Red, a new paid subscription service that Google announced last month that lets users experience the site (and the Music app) without ads for $10 a month.
If you do a search and bring it up on the YouTube Music app, you can toggle a little red "audio only" button on top of the screen that pauses the video so you can turn off the display and put the phone back in your pocket while you listen.
There are some social elements built into the app for now (like the ability to send videos and post them to various social media feeds), but YouTube tells us that as future versions release, you can expect to see more elements like collaborative playlists and friend feeds built into the app.
