Couldn't agree more with all the above comments.
Doesn't Jay Z get it, that with x million subscribers, they may not actually all like rap and hip-hop. I can't stand those genres, yet the Home Page is saturated with it. Tidal does actually have an extensive catalogue now and if you know the album you're looking for you can often find it there, but certainly music discovery that's loosely based around the individual subscriber's own musical taste is non-existant on Tidal.
Spotify used to send me a monthly email giving me a dozen suggestions of albums I might like based on my previous musical choices. They were often albums I came to enjoy. If other musical streaming services can do a bit of scrobbling, surely Tidal can too rather than force-feeding its users with hip-hop they will never want to listen to. The new albums section too is dominated by albums with "parental advisory explicit lyrics" albums that you just know are from the same unsavoury genre.
It's a music streaming service that almost makes it quite tough to find the music you like. Its genre-based music exploration tabs are pretty limited. "Folk and Americana" are under the same banner so although I like folk, most albums there are bluegrass and country style which I'm not really into.
I feel a certain loyalty to Tidal as I subscribed to them before Jay-Z took over purely for SQ reasons, but like the others posting here, its SQ is the only reason I'm sticking with it and if Spotify took the plunge into CD quality streaming, I would definitely jump ship. Tidal needs a major re-design of its front-end that excludes Jay Z from the design process. Message to Tidal staff: next time he's on holiday or ill, change it without him knowing!
