It's mostly okay. There are a couple of issues that make it quite difficult to use as your main music player. First, I hate the fact that it is intertwined with youtube in some way, so my songs won't autoplay in my car or anything if I've recently opened youtube. Really frustrating. Other music players can allow autoplay when you connect to a device. This means I have to manually open the app whenever I have recently watched a YT video. Such a dumb feature. Second, I live in an area without much network coverage. I have downloaded songs and playlists, but YTMusic does NOT automatically switch to your downloads when you lose signal. In fact, it won't even let you listen to your downloaded music unless you specifically go into your library and select Downloads. This is pretty annoying. It means that if you leave cell coverage, your music just stops. You need to open the app, go to "library"->"dowloads"-> and select a playlist in order to start your music again. I'm not a fan of that. There really needs to be a setting for "switch to downloads when I lose connectivity" and be done with it.
