We haven’t heard much from M.I.A. since her March track release, “Can See Can Do,” but now she’s shared a skittering new demo called “Platforms.” Filled with astute observations like, “The tech dudes are the only ones having a good day / And talking is cheap / Coz they make it easy,” “Platforms” mainly sounds like a chant-y discussion of the ways content gets distributed today and how nobody looks each other in the eye anymore. Because, of course, they’re too busy checking their iDevices and sharing music on SoundCloud. (Cough, cough.) Hear it below.
