Jay Z's beloved Blueprint series — a collection of albums that includes the 2001 classic The Blueprint, 2002's The Blueprint 2: The Gift & the Curse, and 2009's The Blueprint 3 — is now only available on Tidal. The albums' disappearance from services like Spotify, Apple Music, and Google Play Music was discovered and reported by Pitchfork earlier this afternoon, and the albums are joining the rapper's 1996 debut Reasonable Doubt as Tidal exclusives. (They're also unavailable to purchase through digital music stores like iTunes and the Amazon MP3 store.)

Reasonable Doubt was pulled from Spotify last April, but the remainder of Jay Z's catalogue has remained intact on other services until now. "Jay Z's Blueprint albums have not been available on any streaming service except Tidal for a few months now," said a Spotify representative in a statement to Pitchfork. "We hope he brings them back soon so that his millions of fans on Spotify can enjoy them again." The Verge has reached out to Tidal for comment.

It's unclear why it took so long for the Blueprint series' disappearance to be discovered, but the move certainly fits Tidal's recent exclusive-centric strategy. Rihanna's ANTI, Kanye West's The Life of Pablo, and Beyoncé's single "Formation" have all enjoyed exclusive debuts on the service in recent months, and West's album is supposed to remain a Tidal exclusive in perpetuity. Jay Z is Tidal's principal owner, so it makes sense that he'd use his own popular catalog to help the service gain a leg up. His stepwise approach to full exclusivity is a little confusing, but if you're a non-Tidal subscriber, I'd still recommend satisfying your musical craving sooner rather than later. It could be a matter of time before all of his music is Tidal-only.
