I believe that when you're making a mix, you're making history. You ransack the vaults, you haul off all the junk you can carry, and you rewire all your ill-gotten loot into something new. You go through an artist's entire career, zero in on that one moment that makes you want to jump and dance and smoke bats and bite the heads off drugs. And then you play that one moment over and over. A mix tape steals these moments from all over the musical cosmos, and splices them into a whole new groove.
