I'm a subscriber, mostly because of YouTube Music. I wanted a music platform where I get push notifications of new music by artists I follow. This feature is broken in Spotify and they have no plans to fix (their words). It seems like a simple enough request, but it turns out this feature is also not available and/or broken in YouTube Music. I keep the subscription SOLELY to watch YouTube ad-free now, and for that it is awesome; but I'm considering switching to another music platform. It's hard for me to cancel my subscription to YouTube though because removing all the ads from YouTube is the only thing that makes it actually useful as a platform.
