Jay Z, whose real name is Shawn Carter, would become a member of Square's board of directors.

Square did not disclose the percentage of the ownership stake.

Dorsey tweeted about the deal Thursday saying quote:

"Why would a music streaming company and a financial services company join forces?!... It comes down to a simple idea: finding new ways for artists to support their work. New ideas are found at the intersections, and we believe there's a compelling one between music and the economy. Making the economy work for artists is similar to what Square has done for sellers."

Jay-Z also tweeted about the pact saying quote: "Jack is one of the greatest minds of our times, and our many discussions about TIDAL's endless possibilities have made me even more inspired about its future."

Square said in a statement that Tidal will operate independently within Square and existing artist shareholders will be the remaining stakeholders.

Tidal - which Jay Z bought for roughly $56 million dollars in 2015 - calls itself an artist-owned service backed by Kanye West, Beyoncé, Madonna, Rihanna and Nicki Minaj among others, and is available in more than 56 countries.
