Even before Taylor Swift's fifth album, 1989, hit one week on store shelves, it's already on track to hit $1 million in sales, and it has been receiving rave reviews.

Billboard reveals that the pop sensation's new album will sell one million copies within the first week, making it the first album in 2014 to reach that level, which will dub Swift as the only singer in history to have ever achieved a one-million-in-a-week feat.

While 1989 sold over 400,000 copies in the first 24 hours, her previous albums did not fair nearly as well. Her Speak Now album which released in 2010 sold 1.05 million copies, while 'Red' which released in 2012 sold 1.21 million copies.

Evidently, other singers over the years have failed to hit that benchmark, like Kanye West's Yeezus and other big pop singers like Beyonce, Justin Timberlake or Lady Gaga, no artist has sold so many, so fast. Also, no single artist have been able to pull off a platinum album this year.

AV Club shares that Swift successfully made the transition from country sensation to pop superstar as proven by the success of 1989.

Swift, New York City's newest Global Welcome Ambassador's previous records have been less and less country, "Nashville-sounding," and more pop and modern (which was a refreshing change). Evidently, the first single on the album, "Welcome to New York," encompasses some of the changes in the singer's life.

Rolling Stone's Rob Sheffield states that Swift's 1989 "sounds like Taylor Swift, even when it sounds like nothing she's ever tried before."

The success of 1989 is reportedly brought about by Swift being a "perfectionist," with the way she dresses, and her "perfect" inspirations for the record which includes Madonna, Fine Young Cannibals, and Annie Lennox.

1989 also showcases an entirely different, more mature Swift. According to AV Club, "She's not necessarily looking for her Mr. Forever anymore. She's just looking for someone she can have some fun with now, seemingly fine with the fact that any relationship is either 'gonna be forever' or 'go down in flames.'"
