Its four-song EP, "She Looks So Perfect," is due out April 1 in the United States on Capitol Records.
The set could sell upwards of 150,000 to 200,000 copies in its first week, according to industry forecasters (if not more).
That sizable prognostication is based partly on robust pre-orders of the set in the iTunes Store, in addition to first-week performance of comparable albums, media exposure, radio and YouTube trends for an album's first single, and so on.
As always, a forecast can be wildly different from the final outcome. In general, you can best guess an album's debut sales week once it's actually on sale.
The buzz around the EP debut equates to a 68% rise in weekly conversation across Facebook and Twitter about the band, which helped lead to the addition of more than 128,000 fans on Facebook (up 62%) and 59,000 on Twitter (up 55%).
The band's current single, "She Looks So Perfect," is bubbling under the threshold of the Pop Songs airplay chart (known as Mainstream Top 40 on billboard.biz and in Billboard magazine). In the week ending March 23, the song was being played on 32 monitored top 40 stations, including KIIS Los Angeles, WBBM Chicago and WIHT Washington, D.C.
