Pretty much the biggest collaboration  to hit Nigeria this year is “Let’s Get This Party Started,” featuring the biggest names in Lagos hip-hop. Kanye collabotor D’banj teamed up with legend MCs 2face, Wizkid, M.I., and Tiwa Savage for the party track, and if you’re a Naija hip-hop fan this is kind of the Mt. Olympus of collaborations. It premiered on Not Just OK this week, where you can download it for free.
