As you may recall, Jay-Z, Kanye West, and a number of other artists recently launched Tidal, a new streaming service that was, at least in part, artist owned. Well, now they're being sued. A proposed class action suit was filed last Friday on behalf of Tidal user Justin Baker-Rhet. The crux of the suit is that Kanye West promised that Tidal would be the only place where people could hear his new album The Life of Pablo. However, following this, West, or his record label, made the album available in other places, including Tidal competitor, iTunes. One portion of the suit's prayer for relief is the deletion of data on every user that listened to the album via Tidal. The suit clams this information alone is worth up to $84 million.
