Kanye West once declared that The Life Of Pablo would only be available on TIDAL.

That turned out not to be true.

But it did heighten the surprise last night when the album was removed from the streaming service.

It turns out there was a perfectly good -- if unusual -- reason for this.

'Ye was re-configuring the album so he could add the track 'Saint Pablo', which is produced by Mike Dean and features Sampha. The now 20 song album is back on TIDAL.

"This is a living album and we’re delivering a new update to the album, as we said we would," a source told Billboard about the song's addition.
