Kanye West dropped his street banger "All Day" in spectacular fashion (at the BRIT Awards while surrounded by mad goons dressed in all black and flamethrowers) and it appears as though one Kendrick Lamar will be appearing on the remix of the track. That's right, the To Pimp a Butterfly emcee is on the remix of 'Ye's "All Day." No word as to when the official, version drops but we're guessing it's just gonna drop outta nowhere -- given the latest music release trends of the past couple years. You can check out a snippet below, which contains a lyrics from Kendrick that goes: "Chi-Town, we play for the free base/These days don't believe what police say/DJs and the b-boys rush it." Get at it!
