Taylor Swift and Carrie Underwood may be country princesses, but according to a list compiled by Rolling Stone, they are two of the current reigning "queens of pop."

The publication recently gathered information in order to find out who the ultimate queen of pop is nowadays. After gathering figures from "album and digital song sales, Hot 100 rankings, radio airplay, YouTube views, social media, concert grosses, industry awards and critics' ratings" from the past two years, Rolling Stone came up with the 16 solo female artists who are the prevailing names in pop music today.

Although they were only listed in alphabetical order and not according to the actual calculated numbers, both Swift and Underwood made the cut. The country cuties are in good company too. Some other women who were named the "queens of pop" are superstar songstresses like Adele, Katy Perry, Beyonce, Rihanna, and many more.

It's easy to see why Ms. Swift was included on the list, considering the 'Mean' singer topped the Billboard album charts in 2010 with her LP 'Speak Now' and is selling out arenas on her 2011 summer tour. Underwood also saw her 2009 'Play On' album soar to the top of Billboard's album charts, and her Play On tour grossed nearly $20 million from 2010-2011.
