The 99 Problems hitmaker bought the brand for around $56 million (£35 million) and relaunched the firm in March (15) with the backing of investors including his wife Beyonce, Madonna, Rihanna, Kanye West, Nicki Minaj, Daft Punk and Alicia Keys, among many other artists.

While its highly-publicised launch initially helped the app find success, sales eventually plummeted, leaving many critics to dub Tidal a failure. Jay Z has stood by his company, insisting it is "doing just fine", but fellow rapper 50 Cent has weighed in and thinks he could have helped Jay stay at the top.

In a recent interview with Los Angeles radio station Real 92.3, 50 Cent said, "We probably could've did something more exciting if they reached out, because the people you saw there don't even own the rights to their music. So they can't say it's gonna come out of Tidal. It has to go everywhere. So why would you actually buy Tidal to get something that would be everywhere else?"

Moreover, 50 Cent, who said he owns all the rights to his music, unlike a majority of artists who are Tidal investors, suggested that Jay only invited artists who have currently released new music, adding, "Usher was there and Madonna and all these people. That's a little bit more of a, when you say, 'It was business', it's more of a corporate play. When the record is playing on the air, they say, 'Oh alright. Let's get this guy.'"
