Now we know why Kanye West hates Jay Z with a passion. Kanye went on a Twitter rampage, posting his contracts and urinating on his Grammy Award.

@lavidaNOTA, who calls himself The Authority, is a South African record label owner who read over the contracts that Kanye posted on Twitter.com this week.

@lavidaNOTA writes, "I have 16-years experience in the music business... It took me all night to understand Kanye's contracts. Aspiring artists have no idea what they are getting themselves into. This is why it’s important to ask people who have been through it for advice!"

Apparently, Jay Z sold the masters to Kanye's first six albums just so he could get his own masters back.

"Kanye contracts SUMMARY: Apart from the inducement which Kanye had to sign to get his advances. This shows that Jay Z sold the masters to first 6 @kanyewest's albums just so he could get his own back. He did so knowing Def Jam won't sell them back to Kanye in future. That's BEEF!"

"[Kanye] owns album[s] 7-10 but the most lucrative and most critically acclaimed albums are owned by Roc-A-Fella which is wholly owned by Def Jam... The majors will never sell you your masters because that’s what gives them market share and drives profits and Jay Z knew that."

@lavidaNOTA says Twitter CEO Jack Dorsey banning Kanye from Twitter had nothing to do with him posting a Forbes editor's phone number.

"Jack Dorsey aka @jack was jogging with Jay Z just a few weeks ago. Now Kanye is banned from tweeting for 12-24 hours. Sounds about rights!"

Kanye West was temporarily banned by Twitter after he shared a screenshot of a journalist's phone number.

The ban came after Kanye went on a tweeting rampage over the past few days that including a video of himself urinating on a Grammy Award and posting screenshots of his recording contract.

On Wednesday, Kanye shared a screenshot of a phone number belonging to Forbes magazine chief content officer Randall Lane. He wrote: "If any of my fans want to call a white supremacist... this is the editor of Forbes."

Kanye was temporarily banned from the social media platform until he logged in and deleted the tweet.

As of Wednesday afternoon, the offending tweet had not been deleted, but Twitter has hidden the tweet from public view.

Earlier in the day, the 43-year-old mega producer tweeted a video that showed him urinating on one of his 21 Grammy Awards submerged in a toilet bowl.

"Trust me... I WONT STOP," Kanye wrote alongside the video clip.

The father of four also complained about his recording contract.

"90% of the record contracts on the planet are still on a royalty A standard record deal is a trap to NEVER have you recoup, and there’s all these hidden costs like the ‘distribution fees’ many labels put in their contracts to make even more money off our work without even trying."

According to Showbiz411, Kanye received a $12 million advance in 2012 for his 2013 album Yeezus - that went on to sell just 609,000 copies in 7 years.

Megan Thee Stallion is fed up with her record label jacking her around. The Instagram model says certain execs at her record label, 1501 Certified Entertainment, have a rep for "bullying and strong-armed tactics," with their artists.

She's taking the label to court, and she's already won a major legal battle, TMZ reports.

A district judge in Harris County Texas granted Megan a temporary restraining order which prevents her record label from blocking the new music she plans to drop on her own on Friday.

Megan filed a lawsuit Monday against 1501 and its boss, Carl Crawford. She was upset about the contract she signed with the label back when she was only 20 and fresh out of the strip club.

In a tearful video on Sunday, she claimed the label was blocking her from releasing new music because she wants to renegotiate her contract for more money.

Megan confessed she made the same rookie mistake as other eager young rappers who just want a record deal.

In exchange for signing the contract with 1501 Certified, she got a measly $10,000 advance -- big money to her at the time.

In the suit, Megan, 25, lays out what she believes are unfair terms of her contract. For instance, she claims the deal calls for 1501 Certified to get 60% of her recording income. The remaining 40% goes to her, but she has to pay engineers, mixers and featured artists out of her 40%.

According to the suit obtained by TMZ, the contract calls for all monies from Megan's touring and live performances to be paid directly to 1501 Certified.

She says the label is supposed to give her a proper accounting of what she's owed -- but claims what they've provided is incomplete, and "purposefully and deceptively vague."

Megan also claims Crawford has been using his relationship with Rap-a-Lot Records founder J. Prince to intimidate and strong arm people in the industry.

She's suing Carl and his label for at least $1 million in damages. J. Prince is not named in the lawsuit.

Megan scored a viral hit "Hot Girl Summer" last year when she teamed up with Nicki Minaj and Ty Dolla $ign.

"When I signed, I didn't really know what was in my contract. I was young, I think I was, like, 20," she explained in the emotional post. "So when I got with Roc Nation (JAY-Z's entertainment and management company), I got management, real management. I got real lawyers, and they were like, 'Do you know that this is in your contract?' And I was like, 'Oh damn, that's crazy, no I didn't know.'"

The "All Dat" rapper didn't specify which terms she objected to, but explained she wanted to adjust the contract to remove certain clauses.

"As soon as I said I wanna renegotiate my contract, everything went left. It just went all bad," she said, as she fought back tears. "So now they're telling a b**ch she can't drop no music. It's really just, like, a greedy game.'

She also clarified that she wasn't trying to leave the record label, but she just wanted a more equitable (read: lucrative) contract.

"I'm not a greedy person. I'm not a person that likes confrontation," she said, adding, "I'm nice and I'm real family-oriented."

Rapper Mase aired out his former boss, Sean "Puffy" Combs, calling the 50-year-old music mogul a hypocrite over his allegedly unfair business practices.

Mase, whose real name is Mason Betha, called out Combs after the mogul rejected his offer of $2 million for his music publishing.

Mase, 44, responded to Combs receiving the Recording Academy's Salute to Industry Icons award at the Grammy Awards on Sunday. He was annoyed when Combs vowed to give control back to artists.

The "Harlem World" rapper posted a photo of Meek Mill along with a tweet referencing "young Black kids in slave contracts in the music business."

"I heard your #Grammy speech about how u are now for the artist and about how the artist must take back control. So I will be the first to take that initiative," Mase wrote in a lengthy open letter to Puffy on Friday.

"Your past business practices knowingly has continued purposely starved your artist and been extremely unfair to the very same artist that helped u obtain that Icon Award on the iconic Badboy label. For example, u still got my publishing from 24 years ago in which u gave me $20k. Which makes me never want to work w/ u as any artist wouldn’t after u know someone is robbing you & tarnishing your name when u don’t want to comply w/ his horrendous business model."

Mase went on to describe offering Combs $2 million for his publishing, but Combs rejected his offer.

"To add insult, u keep screaming black excellence and love but I know love isn’t free. So I offered u 2m in cash just a few days ago to sell me back my publishing(as his biggest artist alive) that always show u respect for u giving me an opportunity at 19 yrs old. Your response was if I can match what the EUROPEAN GUY OFFER him that would be the only way I can get it back. Or else I can wait until I'm 50 years old and it will revert back to me from when I was 19 years old. You bought it for about 20k & I offered you 2m in cash. This is not black excellence at all. When our own race is enslaving us. If it’s about us owning, it can’t be about us owning each other. No More Hiding Behind "Love". U CHANGED? GIVE THE ARTIST BACK THEIR $$$. So they can take care of their families."

@diddy I heard your #Grammy speech about how u are now for the artist and about how the artist must take back control. So I will be the first to take that initiative. Also, before we ask of other ethnicities to do us right we should do us as black people better. Especially the creators. I heard u loud and clear when u said that u are now for the artist and to that my response is if u want to see change you can make a change today by starting with yourself. Your past business practices knowingly has continued purposely starved your artist and been extremely unfair to the very same artist that helped u obtain that Icon Award on the iconic Badboy label. For example, u still got my publishing from 24 years ago in which u gave me $20k. Which makes me never want to work w/ u as any artist wouldn’t after u know someone is robbing you & tarnishing your name when u don’t want to comply w/ his horrendous business model. However, people would always ask what’s up w/ Mase? So I would be forced to still perform to not look crazy when I was getting peanuts and the robbery would continue. So many great moments and people lives in music were lost. But again, I rode with u in the face of death without flinching & u still wouldn’t do right. I never said anything because I wanted to wait until I was financially great so I can ensured that I was addressing this from a pure place and not out of spite. To add insult, u keep screaming black excellence and love but I know love isn’t free. So I offered u 2m in cash just a few days ago to sell me back my publishing(as his biggest artist alive) that always show u respect for u giving me an opportunity at 19 yrs old. Your response was if I can match what the EUROPEAN GUY OFFER him that would be the only way I can get it back. Or else I can wait until I’m 50 years old and it will revert back to me from when I was 19 years old. You bought it for about 20k & I offered you 2m in cash. This is not black excellence at all.
