I don't know if OP or anybody else mentioned this, but there's also a story from Noreaga himself (forgot what interview), but Nore himself stated that Biggie was gonna be on the remix to Capone-N-Noreaga's T.O.N.Y.
According to Nore, Biggie called him days before his death:
"
“I watched the movie [Notorious] a couple of times,” N.O.R.E. told Radio.com. “The only part that made me cry was when he was making those phone calls. I was one of those phone calls.”
In the scene, Biggie placed calls to several of his loved ones. While the call to N.O.R.E. was omitted on screen, he remembers it well. When Big called, he played “T.O.N.Y. (Top of New York),” which was an unreleased song of Capone-N-Noreaga‘s at the time.
“I wasn’t honored that Big called me playing ‘T.O.N.Y.,’ I was like ‘How the fukk you get that?’ I’m thinking it’s bootlegged. Big Took like five minutes before he answered.”
After delighting in N.O.R.E.’s anxiety about his unreleased song, Biggie explained that he was sitting next to the song’s producer Nasheem Myrick. He then dropped the bomb on him.
“He was like, ‘I’m getting on the remix,” N.O.R.E. said. “‘As soon as I get back to New York, I’m bodying that. Don’t tell no one I don’t want nobody to know.’ I’m thinking I’m gonna have the biggest record out.”"
Biggie was just way ahead of his time, I heard the blends with Metro Boomin beats and there's another one that Mister Cee mixed somebody's blends that had him over today's hit beats...and he just had it all man. Gone way too soon.
uuugh we woulda FINALLY got Capone and Biggie on the same track....
