Frank Ocean is being sued by a producer who claims the R&B singer/Odd Future crony aped his music on "Lost," featured on Ocean's Grammy-award winning album channel ORANGE, reports

The lawsuit was filed on March 6 in Los Angeles by producer and songwriter Micha Otano. Otano alleges that Ocean copied his song titled "Daylight" and turned it into "Lost." In addition to Ocean, the lawsuit also names producer Malay, Island Def Jam and Universal. 

The album's liner notes don't specify the producer, but they do credit Otano as a "Lost" songwriter.  See the full lawsuit here.
