Musician Casey Rain called out Jay-Z in a lengthy, since-deleted Facebook post Friday for his accusations against the Prince estate on the song "Caught Their Eyes." In his rant, Rain alleged that Jay-Z attempted to "rewrite history" with his criticisms of the estate.

The rapper has endured an ongoing legal battle with the Prince estate over the late singer's digital music catalog. Jay-Z has used his latest album 4:44, which debuted Friday, to address several issues that have plagued him, more specifically his battle with the Prince estate over the late artist's discography.

Rain is a British musician who is influenced by Prince. He also serves as a staff writer for fan community Prince.org. Rain, also known as S-Endz, doesn't have a large following on social media. His verified Twitter handle has roughly 6,000 followers, with his Instagram and Facebook profiles bringing in slightly over 2,000 each. His music falls within the electronica and pop vein.

On "Caught Their Eyes," Jay-Z blames the estate — primarily former advisor Londell McMillan — for not holding to Prince's wishes to have his digital catalog available on Tidal, the rapper's premium music streaming service. Hov offered a reported $40 million for the Prince's music collection, according to an October 2016 report from TMZ. Following Prince's death, Jay-Z went up against the estate in a Minnesota court over the deal.

"Everyone knows the Prince Estate, family, and Paisley Park is problematic. But Jay-Z throwing shots on his new album is him trying to rewrite history," Rain wrote in the Facebook post. "He can complain all he wants, but the fact is, he offered a pathetic amount of money for the vault which would have barely covered one-third of what the IRS was coming for."

Rain's rant didn't end there, as he proceeded to criticize Jay-Z's alleged decision to release what TMZ reported to be 15 of Prince's lesser-known album's illegally on Tidal.

"Furthermore, he talks about sitting down with Prince before he died but neglects to mention that he started putting bootlegs up on TIDAL Prince died as well as they had no rights for," he added. "Not down with this nonsense from Hov."

With help from R&B singer Frank Ocean taking thing the chorus, Jay-Z told his truth on "Caught Their Eyes." In it, he discussed how he "sat down with Prince, eye to eye" to discuss the Tidal deal.

"He told me his wishes before he died / Now, Londell McMillan, he must be color blind / They only see green from them purple eyes / They eyes hide, they eyes high / My eyes wide shut to all the lies / These industry n—s, they always been fishy," Jay-Z said.

He added: "This guy had 'Slave' on his face / You think he wanted the masters with his masters? / You greedy bastards sold tickets to walk through his house / I'm surprised you ain't auction off the casket / Don't big bro me, don't "Big Homie"/ I've seen pure admiration become rivals / I've been to Paris at least two times / I've seen the Eiffel, I've seen a eyeful."

According to Rolling Stone, Jay-Z's company Roc Nation created a petition in 2016 for the "court to enforce what they claim is an agreed-upon arrangement with Prince concerning his digital catalog." However, TMZ noted that the estate filed a separate petition regarding their desire to not have "Roc Nation to exploit any of the intellectual property assets of the Estate."

The estate wanted Prince's music to be available on multiple streaming services to increase revenue opportunities, not just serve as a Tidal-exclusive deal.

Prince died without a will in sight. Rolling Stone also noted that McMillian, a lawyer who served as the estate's advisor, realized that there was never a physical agreement made between Prince and Jay-Z over the late singer's digital collection. Likewise, the deal didn't end up falling in line with Hov's initial plan.

Nonetheless, "Caught Their Eyes" seems to provide an inside look at Jay-Z's side of the story.
