Music mogul Jay Z‘s Tidal is reportedly under fire from fellow executive Birdman‘s Cash Money Records over copyright issues.

According to reports, Baby‘s Cash Money has sued Tidal for $50 million over streaming estranged artist Lil Wayne’s FWA album without proper permission.

According to the lawsuit, Tidal has claimed Cash Money does not have a exclusive lock on Wayne … Tidal claims Wayne specifically gave it the right to stream his music, in return for part ownership in the company. Cash Money begs to differ, and the company quotes portions of its contract with Lil Wayne in the lawsuit. The contract specifically says Wayne does not have the power to license his music to anyone else. (TMZ)

Wayne’s highly-anticipated Lil Weezyana Fest concert will be live streamed through Tidal in August.

“I’ve connected with my fans in such a cool way with the help of Tidal, and with this Tidal X I can’t wait to bring them another experience,” states Lil Wayne. “Lil Weezyana Fest is so special to me and I’m excited to share it with fans in New Orleans and online.” (AHH)

Hot Boys’ Turk spoke to SOHH last week about how the reunion concert came together.

“That’s official. It’s time for it. We’ve all been working and it was in the works, it was just about finding the time that we were going to do it. [Lil] Wayne decided to do it for the anniversary of Hurricane Katrina and gave everybody a call – me, Juvenile, Mannie Fresh, B.G., he’s locked up, but of course we were ready to do it because it was time for it.” (SOHH)

The announcement came days after Wayne released his FWA project on Tidal.

The 15-track FWA features appearances by Young Jeezy (“White Girl”), Wiz Khalifa (“Feeling Right”), Young Money associate Cory Gunz, Jim “CAPO” Jones and Black Uhuru’s Junior Reid (“Murda”), singer/songwriter Jake Troth (“My Heart Races On”), “B*tch Better Have My Money” writer Bibi Bourelly (“Without You”) and others. “I honestly gotta say that this #FWA album is my best work yet! I won’t let u down as a fan,” Weezy tweeted in April. “Dis sh!t is a beast! Ok let me get bak 2da booth.” (Rolling Stone)
