I've paid for YouTube premium since 2017. It's worth it, for me. I don't need Spotify or any of the other music apps, bc I can find pretty much anything I want on YouTube, and I can lock my phone and everything still plays. I can make playlists of everything I want to listen to and lock my phone and let it ride.
Of course, this doesn't help for watching anything on a TV, so, sucks for all of you lol. Since I really subscribe for the music, anything I watch on a TV is ad free as well, and that's a bonus. YouTube with ads is something I forgot about a long time ago.
