Thank you, Life + Times. It's about time we got something new from Santigold. Yesterday, her new single"Go" (featuring Yeah Yeah Yeahs' Karen O.) appeared on Jay-Z's new lifestyle site. A bit reminiscent of M.I.A.'s recent tone (she frequently references power and status), "Go" prompts immediate head nods -- even if it's darker than her previous singles -- replete with a trademark '80s hook. The formula is simple: Santi sets 'em up, Karen knocks 'em down. Check it out.
