I have Googled your information:
‘’Jay-Z's music is not available on Spotify because of a few reasons. For one, Jay owns his own streaming servive, Tidal, and having his music on the largest music streaming platform in the U.S.(Spotify) would not benefit his business.”
It’s sad that he owns the song while Alicia Keys deserves the credits.
If there are other songs you can't listen to or can't even find on Spotify, please go back to this help article to read more on that.
Thanks and happy listening y'all!
