The "song of summer," by Billboard or iTunes measures, will likely be Ed Sheeran, Iggy Azalea or some other chunklet of boombox fluff. But in our hearts, and in some alternate Earth utopia (Scandinavia?), the jam of heat season, 2014, is Robyn & Röyksopp's "Do It Again," a bubblegum banger that's as big and pink and chrome as Jeff Koons statues breakdancing on your lawn as you BBQ. The Swedish pop pixie and Norwegian electronic duo go back, having collaborated on tracks "The Girl and the Robot" and "None of Dem." Now the threesome has blossomed into a record, the new Do It Again. They're dubbing it a mini-album, but it's 34 minutes long and there's nothing miniature about the hooks or rhythms.
