In response to the tweet Spotify said: "We can confirm that some of Jay Z's catalogue has been removed at the request of the artist /LP".
The hip hop star has had his catalog of solo albums pulled from both the Apple Music and Spotify services, seemingly in favor of Tidal, the music service he co-owns. A handful songs that Jay Z did with other musicians, such as "Holy Grail" which featured Justin Timberlake, are still available on Apple Music.
Jay-Z, a.k.a. Shawn Carter, is part owner of Tidal, a music streaming service that competes with Apple, Spotify, and Amazon's services.

The missives were posted online and a person familiar with the situation confirmed them as authentic to The Associated Press. It is very unusual for a committee chairman and ranking member not to coordinate meetings related to an investigation.
The move comes as Tidal, the company Jay Z launched in 2015 and heavily invested in, remains a distant finisher in the opaque streaming marketplace.
Late last month, Apple Music had an estimate of 40 million users on mobile, putting it ahead of Spotify, despite Spotify's claim that it has 50 million paying subscribers versus a total 20 million for Apple.
It isn't clear if this latest move is specifically meant to drive up Tidal subscriptions. It's not clear if the service simply hasn't yet pulled the catalog, or if Apple Music and Spotify were targeted specifically for being the two biggest players in the streaming market, and therefore the toughest competition for the struggling Tidal.
