6ix9ine has an unreleased track in the stash with Danish artist Sleiman, but apparently, 6ix9ine's label won't let it see the light of day—and Sleiman isn't happy about it.

According to a report TMZ published on Thursday (April 18), Slemain has filed a lawsuit over the song against 6ix9ine and his label, 10k Projects, to the tune of nearly  $100,000.

The celebrity news site reports that 6ix9ine recorded the song for Sleiman in September of 2018—just before a couple months before Tekashi was arrested in the federal racketeering case that still has him behind bars. According to the lawsuit, 6ix9ine was paid 88,000 euros for the feature, which equates to just under $100,000 USD.

Unfortunately, once "Red Bandnna [sic]/Black Hoodie" was fully complete, Sleiman claims that 10k Projects reached out to him and said they have exclusive rights to all things 6ix9ine, and that the song couldn't be released unless they signed off on it.

10k Projects reportedly added that if he did release it without their approval, they'd quickly sue him. Months later, Sleiman still doesn't have their approval and is now sitting on an unreleased track that he's already paid for, and he wants a judge to declare him the rightful owner of the track so he can release it. He also wants the money back that he paid to 6ix9ine for the feature—for his troubles, of course.

6ix9ine currently remains behind bars, but his lawyers recently revealed hopes for a different plan. Dawn Florio, a member of the rapper's legal team, said in a statement to TMZ that if his co-defendants take plea deals, she will ask a judge to grant 6ix9ine time served since he's been behind bars since November 2018. Should all go well, 6ix9ine could be a free man as early as September.

XXL has reached out to 6ix9ine's reps for comments on the lawsuit.
