(AllHipHop News) Atlanta-based producer Bangladesh has reunited with rap star Lil Wayne for the release of Weezy's latest track "6'7," the first single from the upcoming album Tha Carter IV. The track, which is the first release from Lil Wayne's highly anticipated album Tha Carter IV, features Young Money label mate Corey Gunz. The pair's relationship became strained when Bangladesh accused Lil Wayne and Cash Money Records for failing to pay over $500,000 in royalties for the hit single "A Milli." Bangladesh, born Shondrae Crawford, called Lil Wayne and cash Money "devils" in May of 2010, shortly after the lawsuit was filed."I wasn't getting paid royalties, that was the issue. But recently it's been cleared up and everything that's owed will be paid out and everything in the future will be handled properly," Bangladesh told AllHipHop.com. "It wasn't me who made this decision, Lil Wayne wanted these beats, because I didn't know what the relationship was."Bangladesh has produced tracks for Nicki Minaj, Sean "Diddy" Combs, Fabolous and even Beyonce Knowles ("Diva").Now that the contractual issues are cleared up, Lil Wayne and Bangladesh have resumed their working relationship.Their latest collaboration "6'7," incorporates Harry Belafonte's hit song "Banana Boat Song," was actually delivered to Lil Wayne through Atlantic Records' executive, Gee Roberson.Roberson also heads up influential management company Hip-Hop Since 1978, which also works with artists like Kanye West, Young Jeezy, Nicki Minaj, Drake and others. "It was similar to a Milli. It was so hot, I didn't send it out to anyone because I didn't know who was worthy of this," Bangladesh told AllHipHop.com. "I remember when he was in he was calling me and asking me what the beat was saying, so I was just assume he was writing in jail and they were giving him the information so he could really build off it," Bangladesh told AllHipHop.com."Lil Wayne's album Tha Carter IV is due in stores in February.
