Well, that Green Lantern mixtape we mentioned earlier has now been released and here’s another track from it you might want to check out. “Most Kingz” is a previously unreleased cut from Coldplay frontman Chris Martin and his best friend forever Jay-Z.

According to 2dopeboyz, the track is the product of the same session in which Martin and Jay-Z recorded Kingdom Come‘s “Beach Chair”, but because the Brooklyn rapper could never find a worthwhile accompanying beat, “Most Kingz” remained unreleased. Pieces of the verses ended up on the Grammy Family freestyle on Hot97 w/ Funk Flex in 2006 as well as Coldplay’s “Lost” (rmx). Green Lantern ultimately got a hold of the full track, and you can stream his take on it below:
