In celebration of his 50th birthday, JAY-Z shared on his Twitter account that his entire catalogue is back on Spotify. JAY, who owns the streaming service Tidal, previously removed a majority of his albums, leaving behind Reasonable Doubt, In My Lifetime, Vol. 1, and Vol. 2…Hard Knock Life. He also allowed Spotify subscribers to stream Collision Course, his 2004 album with Linkin Park. Now albums such as The Black Album, American Gangster, and Watch the Throne are available. There is no work on how long Jay’s discography will be on Spotify, so take advantage of the music now.
