Wasn't Major Lazer's Lazer Strikes Back series supposed to be three volumes? That's what we were told initially, but it looks like a fourth just popped up on the 'Net. We can't complain, as it features a grip of heat: a drum & bass remix of "Jah No Partial" by Run DMT, Chronixx hopping on the "Get Free" riddim, a Major Lazer remix of Bunji Garlin's awesomely-titled "Differentology," a weird mash-up of Disclosure and No Doubt from Major Lazer, and a flip of Snoop Dogg & Drake's "No Guns Allowed." Mixed bag, but it's free and it's MAJOR.

And be sure to grab the older volumes: Vol. 1 | Vol. 2 | Vol. 3.
