Taylor Swift has landed on another annual countdown, earning a coveted spot on Forbes' 30 Under 30 feature as one of the most innovative, financially-friendly young musicians of 2012.

Swift, who just turned 23 on Dec. 13, joins the ranks of pop heavyweights Justin Bieber, Adele, Bruno Mars and Marcus Mumford (of Mumford & Sons) on the year-end countdown, which measures the social and financial relevance of young professionals in 15 different categories.

The 'I Knew You Were Trouble' singer's current fling, Harry Styles, also appears on the shortlist of America's top musicians as a collective member of the boyband phenomenon, One Direction.

Earlier this year, Swift was named the wealthiest celebrity under 30 by Forbes, earning a jaw-dropping $57 million in income between May 2011 and May 2012. The singer knocked Lady Gaga from No. 1 -- she held the top-earner title the previous year.

The country music superstar, who recently snagged six World Music Awards nominations, will no doubt remain a strong competitor on Forbes' tally leading into 2013. Swift's latest studio album, 'Red,' has sold more than three million copies worldwide in just two months -- enough to make the collection of the the top sellers in all of 2012.

She is also set to embark on her headlining 2013 Red Tour in March, and will play more than 60 shows before wrapping the road excursion in Nashville next September. With a reported $1 million paid per show, it's likely to expect Swift on next year's countdown as well.
