Two new songs have leaked from the upcoming 'Notorious' soundtrack, including Jadakiss' heartfelt "Letter to B.I.G.," featuring Biggie's former wife Faith Evans. It's hard to believe that "I'll Be Missing You" dropped over ten years ago, but Kiss hasn't lost a step.

The other leaked track is 'Microphone Murderer,' a Biggie demo track that helped get him signed to Uptown. Over a loop of The Emotions' classic "Blind Alley," Big spits some viciousness: "Even on stickups I'm the masked avenger/ Keeps my eyes open and the case closed/ No eye witnesses or names exposed." Even on his demo, Biggie was a pro.
