T-Pain’s record label Nappy Boy Entertainment is reportedly suing Universal Music Group’s Cash Money Records for unpaid royalties, specifically from Lil Wayne's albums Tha Carter III (2008) and Tha Carter IV (2011).
According to TMZ, T-Pain claims that he and Nappy Boy signee Young Fyre are owed more than $500,000 for their work across the two records. In particular, T-Pain produced and was featured on Wayne's "Got Money," which was the latter’s second highest debut and third consecutive top-ten hit from Tha Carter III on the Billboard Hot 100. Young Fyre has co-production credits on “How to Hate” from Tha Carter IV, which also features T-Pain on vocals.
Both Tha Carter III and Tha Carter IV debuted at No. 1 on the Billboard 200 chart and have since been certified triple-platinum by the RIAA, selling over 3.5 million copies each by 2009 and 2012, respectively.
