It's not often that a pop reunion draws the consumptive mania that New Kids on the Block is. Understandably, few boy bands have had as much impact on a generation: By 1988, NKOTB was a global phenom, launching merchandising to newfound heights, with nine consecutive top 10 singles in two years, before momentum deflated in 1994. All five original members—Donnie Wahlberg, Danny Wood, Joey McIntyre, Jordan Knight and Jonathan Knight—now in their mid- to late 30s, are in the game for a new album and tour. Ironically, first single "Summertime" melodically and thematically sounds much like "Summer Girls," a top 20 hit in 1999 for rival boy band LFO. It's all right, but enough of a youthful reminder for millions of nostalgic (and financially able) 30-something fans to at least fuel thousands of iTunes downloads of the group's "Greatest Hits" (plenty of videoclips are also available). Whether or not this particular song connects at radio, New Kids' return is a pop culture event—and certain cash cow. It's also good clean fun, and that never goes out of fashion. —Chuck Taylor
