How long can Kanye West and other stars stick with Tidal?

Consider this: Kanye West, one of the biggest artists on the planet, released a new full-length album this month; 10 days later, it hasn't made the Billboard 200 chart.

That's because Tidal, which has the exclusive digital rights to West's album "The Life of Pablo," would not share streaming data with Nielsen. If it did, the numbers would almost certainly be very low.

Tidal launched almost one year ago, in March 2015. Jay Z (Shawn Carter) acquired it when he bought the Swedish "lossless streaming" company Aspiro last year for a reported $56 million. ("Lossless" is a file-compression technlogy that makes the track sound exactly as it does on a CD; standard streaming is only a very close approximation.) Tidal is often called "Jay Z's streaming platform," but there are 15 artists or groups that have equal equity stakes in Tidal: Carter, West, Beyonce, Rihanna, Nicki Minaj, Usher, J Cole, Madonna, Jason Aldean, Arcade Fire, Daft Punk, Deadmau5, Calvin Harris, Chris Martin of Coldplay, and Jack White.

Despite the star-studded lineup, the service has appeared to suffer setback after setback.

First, its much-hyped launch event did more to alienate fans than inspire them. What was intended as an effort to return control to artists instead looked like a bunch of rich mega-stars uniting to cheer for their right to make more money.

Tidal has gone through three CEOs in less than a year: Aspiro CEO Andy Chen stayed on at first, but Tidal let him go after one month; it then appointed a different Aspiro executive, Peter Tonstad, as interim CEO, but dismissed him in June; Jeff Toig, former chief business officer at the streaming service SoundCloud, took over as CEO in January.

In June, reports emerged that the artist Drake (Aubrey Graham) was initially signed on to Tidal but backed out at the last minute to jump ship for Apple Music. In October, Carter was asked to list all of his business interests at a deposition and forgot to mention Tidal—more bad optics. Amidst ongoing negative press since its launch, Carter has repeatedly taken to Twitter to defend the platform. In April, he said Tidal had 770,000 subscribers, and in September he said it had gone "platinum," reaching 1 million users.

Tidal has not provided any update on user numbers since Carter's tweet in October; the company declined to comment for this story and declined to answer basic questions such as how many full-time employees it has. TMZ reported that since West's new album launched, Tidal has ballooned to 2.5 million subscribers, but the report has not been confirmed.
