Good selection, but their algorithm wasn't great. Ex. I would be listening to a metal song, and it would pull up Rolling Stones next.

That's exactly what YouTube Music always did for me. In fact, it would do that after just one or two songs. I tell it to play an artist or a specific album and the 2nd or 3rd song would be completely unrelated, along with everything after it. It was like it never even considered any sort of continuity unless I was playing a specific playlist made ahead of time.

Just started trying Qobuz a few days ago, so it can't possibly be any worse than what I was already dealing with there.
