Who says bubble-gum pop loses its flavor overnight? The scrubbed and prefabricated British boy band One Direction announced a Seattle date on its world tour 15 months ago — in other words, in another era, by pop-kultch standards — yet its platinum albums, “Take Me Home” and “Up All Night,” are still in the Billboard Top 200. With a One Direction movie due in August, preteens are still arguing over who’s cuter — Niall, Zayn, Liam, Harry or Louis — and gleefully hiccupping the “uh-uh-oh” hook to the new single, “Best Song Ever,” which got 10.9 million views on Vevo in 24 hours.First seen as individuals on the 2010 edition of impresario Simon Cowell’s “X Factor” TV show, then handily assembled into a unit, One Direction has revived the boy-band craze epitomized by such old-school groups as ‘N Sync and New Kids on the Block. Reported to have sold 14 million albums to date, the “one direction” this band seems to know is up.
