Kanye will release his new album on Spotify and Apple Music this Friday - unless he changes his mind

After vowing that his new album would only ever be available on Tidal, Kanye is expected to release "The Life of Pablo" in full on Friday to other streaming services like Spotify and Apple Music, according to sources Business Insider talked with who were familiar with the plans.

Two songs from the album, "Famous" and "I Love Kanye," were already available on Spotify and Apple Music.

Tidal has said "The Life of Pablo" was streamed 250 million times in its first 10 days on the service. The album also had 500,000 illegal downloads on its first day alone, according to TorrentFreak.

But fans have been frustrated by its lack of availability on Spotify and Apple Music, which are the two most prominent on-demand streaming services by user count.

It must be noted, however, that Friday is April Fool's Day, and Kanye has been known to change his mind.
