's posted a new Swizz Beats-produced Jay-Z track called "Ultra". Who knows where or when this track will show up again though. Pitchfork thinks the multiple Diddy nods might indicate that the track, or at least part of it, will be featured Sean Combs upcoming "electro-hip-hop-soul funk" album Last Train to Paris coming out on June 29th. Either way, the track, rife with late-90's era rap whistles and a smooth, bouncy bass line, make it pretty bangin' if we do say so ourselves.
