Disco lives! Kylie Minogue coos her way through the best guilty-pleasure retro-dance smash since Eiffel 65's ''Blue.'' With every sound a hook, ''Can't Get You Out of My Head'' fully lives up to its title. Be warned: The track falls far closer to Andrea True than Donna Summer. And Minogue milks the formula dry on the album. But before she does, this longtime Aussie star proves she finally deserves passage beyond America's velvet rope.
