Six months into our relationship, we're still in love with M83's 'Hurry Up, We're Dreaming.' Anthony Gonzalez's sugar-coated epic had everything we could ask for in a love story: saxophone solos, cathedral catharsis, a frog fairy tale. The double album was split by a hidden track called 'Mirror' -- hidden as in tucked away online. This Record Store Day the song will be freed from hyperspace, though in limited quantity: 2,000 copies will be available.
