YouTube Music re-debuted almost a year ago as a promise of unparalleled selection and algorithmic prowess, but it was feature-light and bug-heavy. In the 11 months since, it's been a long and very slow road to fix the bugs and fill in the gaps in the app's performance, with it taking nine months for Android Auto support to be implemented and four months for audio quality controls to roll out to all users. Casting from YouTube Music is still a mess and library management still needs work, but the biggest problem with using YouTube Music as your one and only music service — which is what I've done since setting up my Galaxy S10 — is that offline music, the music you rely on when Wi-Fi fails and signal is spotty, abandons me night after night when I need it most: on exhausted evening drives home.

For most normal music apps, you download music once, and that's that. So long as you connect your phone to the internet more than once a month, the music stays downloaded and you can keep the tunes flowing. YouTube Music is different, partially by necessity. Because YouTube Music relies upon YouTube's video library, it checks downloaded content once a day to ensure that everything downloaded hasn't been pulled from YouTube by the uploader or YouTube staff. The problem here is that when YouTube Music makes this check, it deletes all downloaded music and then re-downloads it again. Every day. YouTube Music can make this check at any time, but it usually does it in the afternoon or evening when the device is plugged in to charge. You'd think this wouldn't be much of an issue — if you're plugging in to charge later in the day, one would assume you're plugging in at home after a long day at work — but plugging in your phone for Android Auto in the car or topping off from a portable battery can trigger these checks, too, as can re-opening the app after clearing it from Recents.
