Lupe Fiasco drops "Peace Of Paper/Cup Of Jayzus" - what looks like a one-off single that features the Chi-Town MC going in over a remake of Jay Z's "Holy Grail" beat. It could be argued that the subject matter of Jay's latest project may have prompted a response from Lupe, considering his penchant for social commentary. Lupe has reportedly been dropping hints about the impending arrival of this track on his locked Twitter account. This joint clocks in at 7 minutes and comes without a hook. He finishes off the track with a bit of speculation on who might be the greatest rapper alive. A hint: the usual suspects are nowhere to be found on his list. Check the track below to listen to the latest from Lupe Fiasco. Stay tuned for more from Lupe and his forthcoming LP Tetsuo & Youth.
