Just read this over on the Steve Hoffman forum

'Noticed more and more albums disappearing from Tidal, is this a sign of their end, they're losing streaming rights and contracts with record labels?
Just a few albums I had in my playlists which are not available any more:
Tosten Goods, Roberto Di Gioa, Tim Lefebvre & Wolfgang Haffner : Thank you Baby!
Momo Wandel Soumah: Afro Swing
Dianne Reeves, Wynton Marsalis: Magic Hour
Hugh Masakela: I am not afraid
Maybe its time to re-evaluate Qobuz …'
Not a streamer myself though can see the attraction in it, but I generally dislike being in the hands of any 3rd party so avoid it wherever possible
