Goofy Danes Jesper Mortensen and Jeppe Laursen elevate the pursuit of innocent fun to a fine art on the second Junior Senior album. Combining the wide-eyed longing of girl-group pop, the playground energy of early rap, and the soaring optimism of vintage disco, the duo tackles heavy-duty issues in seemingly disposable tunes. Aided by members of the B-52’s, Le Tigre, and Motown cult favorites the Velvelettes, the lads use their search for the perfect song to promote self-betterment in “I Like Music (W.O.S.B.)” and achieve dance-floor nirvana on “Can I Get Get Get,” which recalls funk immortals Chic. If the giddy “We R the Handclaps” doesn’t make you smile, it’s time to get professional help.
