Future and Kendrick Lamar inhabit different lanes on the hip-hop superhighway, but they joined forces on the new remix of "Mask Off." DJ Envy debuted the track this morning on The Breakfast Club and the denizens of Twitter took to the timeline to weigh in on Kendrick's verse. The online debate does not primarily revolve around the quality of Kendrick's verse, but rather Future's decision to place him on the remix in the first place.  "Mask Off" peaked at #5... perhaps Future is gunning for that #1 spot.
