Swift serves up "Begin Again," the second single from her fourth studio album "Red," due Oct. 22. Ke$ha's "Die Young" previews her sophomore full-length, "Warrior," due Dec. 4, while Rihanna's "Diamonds" introduces her seventh set, due this fall.
Industry sources say that Swift's "Begin" could sell 300,000 downloads or more by the end of the tracking week on Sunday (Sept. 30). Ke$ha's "Young" could start with more than 200,000, as could Rihanna's "Diamonds."
Predicting the latter song's sales is a bit harder for industry forecasters than the first two, as it was released on a Wednesday instead of Tuesday (the more common label practice). "Diamonds," thus, will launch on next week's Hot 100 and Digital Songs charts with one day less of a sales sum than its competitors. Source
