Born Again is a posthumous album by The Notorious B.I.G. It was released on December 7, 1999. Unlike the first album released after his death (Life After Death), this album was created with no input from Biggie himself. It is composed primarily of unfinished material and unreleased verses recorded mainly during his Ready to Die era from 1993 to 1994, with new production and guest rappers. The album debuted at #1 on the Billboard 200 chart with 485,000 albums sold in the first week, and was later certified Double-platinum. Along with the usual guest roster of P. Diddy, Lil' Kim, and Junior M.A.F.I.A., the album also featured appearances from Nas, Ice Cube, Eminem, Busta Rhymes, Mobb Deep, Missy Elliott, Method Man, Redman, Beanie Sigel, Too Short, Snoop Dogg, and the Hot Boys. Before his death, Biggie had intended his third album to be a three disc collection. However, there was not enough finished material to piece together such a massive project. This is the final album of Biggie to contain mainly original material. However, in 2005, a remix album was released called Duets: The Final Chapter. Despite mixed reviews and some criticism, it was certified double platinum by the RIAA on January 14, 2000. 
The album received moderately poor reviews from critics. Upon its release, Rolling Stone wrote that the "album won't damage his legacy. But Born Again won't improve that legacy much, either." In a retrospective review of his output in 2004, the magazine wrote "The posthumous Born Again proved Biggie was still dead, but his place in the MCs Hall of Fame remains untouchable."Robert Christgau, who gave the release a "dud" rating, later wrote, "Remember that posthumous outtakes CD Bad Boy attributed to Biggie? No? Good then—it was foul, not just ill shit but stupid ill shit."
"Dead Wrong" was an unreleased song from a demo tape back in 1994. The first verse of the original version was used in this version.
Biggie's verse from "Hope You Niggas Sleep" comes from the second verse of the original version of "Dead Wrong".
Biggie's verse in "Dangerous MC's" comes from an unreleased song called "The Ugliest" which was originally going to be on Busta Rhymes' 1996 album The Coming.
