Think Things Couldn't Get Worse for Jay Z's Struggling Streaming Service? They Just Did.Under Jay Z's helm, the company just lost its second CEO in three months.

If Jay Z's got 99 problems, his much-mocked and commercially slumping streaming service Tidal seems like every single one of them.

The latest bout of bad news? Tidal's interim CEO, the Norwegian media executive Peter Tonstad, has left the company after less than three months on the job, TidalconfirmedtoThe Wall Street Journalthis morning.

Tonstad succeeded Andy Chen, Tidal's first CEO under Jay Z's helm, who left the company last April amid a round of about 25 total layoffs. Both Tonstad and Chen previously served as CEO of Aspiro -- the Swedish parent company of Tidal that Jay Z purchased for $56 million in March.

Tidal, which is owned by Jay Z as well as a faction of fellow chart-topping artists including Beyoncé, Kanye West, Madonna and, most recently, Lil Wayne, "will be run by executives in New York and Oslo until a new chief is in place," theJournalreports.

Besides the CEO revolving door, the company, which promises artists higher royalties, is still struggling to get subscribers. TheJournalreports that Tidal counts just 770,000 paying subscribers compared to industry leader Spotify's 20 million.

Tonstad's departure arrives on the heels of a major coup in the streaming world by another artist, Taylor Swift, whopersuaded Appleto change its royalty-paying policies in a beseeching Tumblr post over the weekend.

Given Swift's proliferating sovereignty in the music industry, perhaps Jay Z should consider passing the executive torch to the uber-savvy crooner? Though Swift, who is anotoriously fastidiousbusiness strategist and retweeted a message from Elvis Costello yesterday in which he called her "our future President," may ultimately be casting her eye to an even loftier prize.
