Currently using YouTube Music. It has its share of suckyness, and it seems music only reaches the service if someone actually uploads it, so can claim a copyright strike to monetize it.

But it has its perks. You keep your entire playlist if you ever stop paying. Music is streamed at 256 kbps. The playlist options are quite flexible. You can play offline music. And no ads for YouTube videos!
