The Reference Track: "Ultra," featuring Jay-Z and Swizz Beatz
The Original Plan: For Last Train To Paris, Diddy tapped Hova to contribute a verse and ghostwrite one for him as well. Unfortunately, it's only been leaked with Jay doing verses for both of them.
The Potential: It's got a Too $hort "Blow The Whistle" vibe going on (which isn't a bad thing) and anytime Jay and Puff get together, it's a notable event. Unfortunately, this is just another song for radio DJs to throw on for 30 seconds at a time right now.
