Prince’s 4Ever — the 40-track compilation album that doubles as the Purple One’s first posthumous release — dropped on Tuesday. The greatest hits collection captures his Warner Bros. Records tenure, which spanned 1978 to 1992, and features definitive hits from that period including “Purple Rain,” “1999,” and “Kiss.”

But the compilation also includes “Moonbeam Levels,” a previously unreleased track exhumed from Prince’s vaults. Recorded in 1982 — the year Prince released his double album 1999 — “Moonbeam Levels” made its debut on an ABC News livestream Tuesday morning.

Since his death in April, Prince’s unreleased material has been a subject of intense scrutiny. Many think the prolific artist’s studio output, which totaled 39 album during his lifetime, is dwarfed by the recorded music he never made public. “I know from my past experience that very often some of the material needs significant editing,” attorney Donald David, who represented the estates of Tupac Shakur and Lisa “Left Eye” Lopes, told EW in May. “But you’re going to see unreleased Prince albums — if [the estate] is properly managed — for the next two decades.”

Next year, Warner Bros. will debut more of Prince’s unheard music in a deluxe, remastered edition of Purple Rain, housing a second disc of previously unreleased material. A release notes that plans for the set “were agreed with Prince before he passed away.”
