R&B star Frank Ocean has been hit with a copyright lawsuit over his track Lost

Songwriter Micah Otano claims he teamed up with producer Malay to pen a tune called Daylight, but never received credit for his work when it was allegedly renamed and included on the Grammy winner's debut studio album, Channel Orange.

Otano filed legal papers at the U.S. District Court in California on Wednesday (06Mar13), seeking undisclosed damages and back royalties, according to AllHipHop.com.

Ocean has yet to comment on the lawsuit.
