JayZ owned a small percentage of Tidal, but sold it a year ago.
I’ve never gotten got a message asking "wouldn’t you enjoy listening to some JayZ?"
I’m not into Rap but I went with Tidal for their catalog and the Tidal Connect integration with my streamer. I didn’t really notice a concrete difference in SQ between Qobuz & Tidal. Both have different versions of some tracks so it's likely that some versions sound better than others.
