Since the release of Red Swift's popularity has gone through the roof. The album has sold almost four million copies in the US alone, spawning her first Billboard Hot 100 number one single "We Are Never Ever Getting Back Together" and the hugely popular "I Knew You Were Trouble." In its first week, Red sold 1.208 million copies, making it the highest weekly sales number in a decade, and earning Swift the distinction of being the first female artist to sell over a million copies in an album's first week of release twice, since SoundScan began tracking sales figures in 1991.
