Late pop singer Prince's first posthumously released song Moonbeam Levels was premiered on ABC News on November 22 at New York's Cutting Room Recording Studios.

Since Prince's death on April 21, his unreleased songs have been a significant subject. The pop singer reportedly left hundreds of unreleased songs in a vault at his Paisley Park estate in Chanhassen, Minn.

Prince's first posthumous release titled Prince 4Ever released on November 22 which features 40 songs. The greatest hits collection features definitive hits from the period spanning 1978 to 1992 including Purple Rain, 1999, When Doves Cry and Kiss.

This exclusive collection also consists of one of his unreleased song Moonbeam Levels which is originally recorded in 1982 during the same recording sessions for his hit album named 1999.

According to RollingStone, "Moonbeam Levels is vintage Prince, a stomping R&B ballad filled with striving piano, rousing guitar riffs and ecstatic vocal wails. But despite the musical gusto of Moonbeam Levels, the song has a somber undercurrent, with Prince singing, "Please send all your moonbeam levels to me/ I'm looking for a better place to die."

ABC News premiered the song exclusively for some Prince fans at a listening session at New York's Cutting Room Recording Studios.

A deluxe reissue of Purple Rain is expected to arrive early next year and will include a second album of previously unreleased material.
