Sometimes the greatest things come with little to no fanfare. Case in point the totally unexpected collaboration found on California rapper E-40’s latest album, Revenue Retrievin’: Night Shift. Ok, so it might not exactly be a collaboration, but as HipHopSite.com reports (via Fader), Björk did recently make the incredibly rare gesture of allowing E-40 to sample her music, specifically her 2004 a cappella album Medúlla. You can hear the end result is a Droop-E-produced track called Spend the Night”. Take a listen here.
