Screwheads' The Best of Both Worlds opens into a mixtape-style parade of guest MCs and one-shot collaborations. The slightly odd thing is that this is a screwed-and-chopped remix of an album that doesn't exist in any other form. On the one hand, that means that the screwed-and-chopped style has progressed to the point that it's its own form of music now, not just a method of remixing.
