It looks like the music streaming wars are continuing to heat up. In the latest salvo, Tidal-owner Jay Z has apparently pulled all three albums from The Blueprint trilogy from a number of non-Tidal music services, as reported by Pitchfork. Currently, none of The Blueprint albums are available to stream on Spotify or Apple Music, and have even been taken down from the iTunes store, Google Play Music and Amazon's digital music store. Obviously all the albums remain available on Tidal.

In a statement to Pitchfork, a representative from Spotify said, "Jay Z's Blueprint albums have not been available on any streaming service except Tidal for a few months now. We hope he brings them back soon so that his millions of fans on Spotify can enjoy them again."

This news follows the removal of his debut album Reasonable Doubt from Spotify last year. Aside from these four albums, the rest of his catalog remains available for streaming on all services. There's no official word yet on what prompted the move, but with competition for subscribers continually heating up between the music streaming rivals, it doesn't come as a huge surprise.

What's more shocking is that he would remove the option to purchase them outright. Kanye West, who released The Life of Pablo exclusively through Tidal, recently declared the death of the CD and said his music will only be available to stream from now on, but even that didn't take into account his back-catalog. We'll have to wait and see how this affects relations between the rival services.
