A Kanye West fan sued the rapper and the streaming service Tidal on Monday, saying they duped users into subscriptions based on the promise of being the exclusive outlet for West's latest album.

The proposed class-action lawsuit filed in U.S. District Court in San Francisco by Justin Baker-Rhett contends West fraudulently promised fans that his album, “The Life of Pablo,” would only be available on Tidal. The site charges users at least $9.99 a month, but West's album has since been released for free on Apple Music and Spotify.

Millions of people flocked to Tidal in February because of West's new album and the rapper's promise of exclusivity, giving the struggling site a boost and also a trove of user information, the lawsuit states.

Baker-Rhett is asking a judge to order Tidal to delete information collected on users who signed up for West's album.

“Mr. West's promise of exclusivity also had a grave impact on consumer privacy,” the lawsuit states, noting that users' credit card information, music preferences and other personal information have been collected.

The lawsuit contends the value of new subscribers and their personal information could be as much as $84 million for Tidal.

Email messages sent to Tidal and West seeking comment were not immediately returned.
