Four years after His Purple Majesty’s death, he continues to give us life with “new” music. “Cosmic Day,” released on Thursday, is the latest of Prince’s unreleased tracks to come from the royal afterlife.

Recorded in 1986, the giddy, guitar-charged rave-up — think “Delirious” meets “Let’s Go Crazy” — previews the upcoming expanded reissue of Prince’s classic “Sign o’ the Times” album, due Sept. 25.

A glimpse of the reissue of the 1987 double LP — which features such hits as “U Got the Look,” “I Could Never Take the Place of Your Man” and, of course, the title track —  dug into Prince’s legendary vault with “Witness 4 the Prosecution (Version 1),” a righteous gospel-funk jam recorded in 1988.

Another previous sign of the reissue was a 1979 version of “I Could Never Take the Place of Your Man,” which, in raw form, strips the song down to its basic guitar-pop charms.

The upcoming “Sign o’ the Times” reissue — which follows posthumous re-releases of “Purple Rain” in 2017 and “1999” last year — will come in three remastered editions: the standard original album, a deluxe version and a super deluxe blowout featuring a whopping 63 previously unreleased tracks.

Now that’s a good look for Prince.
