I honestly think this Lost Tapes will be mostly songs that we haven't heard or some hq versions of fan favorites that never made an album i.e. "Rise & Fall", but I think even that's highly unlikely since Nas has been sitting on 6 years of material between Life Is Good and Nasir. With the original Lost Tapes, he was putting out albums every two years on average. If he goes back pre 2012/2013, he has:
-an entire album of material that was cut from Street's Disciple. Reviewers had a copy of Street's Disciple that is different from the retail. "Get Up", the sequel to "Get Down" was on it. There's also "Serious", which leaked and "Talk of NY", which also leaked.
-songs from God's Son we will never hear due to him destroying the sessions. "Honeymoon Is Over (My Will)" leaked (need this no DJ in HQ) and "Ridin Broke" actually came out. "F Hot", Crabs InA Barrell", the original Trackmasters version of "Hey Nas" , and "Curtains" remain unreleased.
- 5 will.i.am songs that didn't make HHID that Nas said were better than anything on the album. "The World Is A Ghetto" ended up on Game's Documentary 2.1. There's also "NY Stomp", "You Mean The World To Me" (a Kanye track that leaked but sounds unfinished)
- "The Scientist" produced by Just Blaze
- an Alchemist track, a will.i.am track, 4 DJ Toomp tracks, and some leaks that didn't make Untitled. There's some more Jay Electronica piano interludes and work with stic.man ("America's Top Brothel").
- the title track for Life Is Good
Then there's post 2012 material like:
- work with Timbaland ("Sinatra In The Sands") and other songs
- an album with Swizz
- work with Large Professor, The Beatminerz, and No I.D.
- work with Reefa and possibly J.U.S.T.I.C.E. League
