Taylor Swift can afford to keep up her Starbucks habit. The 21-year old, currently circling the globe on her Speak Now World Tour, is making more money than all of her country peers, according to Billboard.

Billboard compiled their list of the top income-earners from 2010 based solely on U.S. earnings, including record sales and tours. According to their data, Taylor earned a whopping $20,730,431 last year. The country phenomenon is just about $10 million behind music's top earner, pop phenom Lady Gaga, who raked in $30,556,342. Bon Jovi sit at No. 2 with $30,441,776 in 2010 earnings. Roger Waters takes the third slot, with $24,489,675. The Dave Matthews Band came in at No. 4 with $23,942,353, while Justin Bieber rounds out the Top 5 with $22,492,565.

Taylor isn't the only country star who celebrated the end of 2010 with a larger wallet. Nashville residents take over the Billboard list from No.s 12 - 14, with Brad Paisley making $13,955,990, Carrie Underwood right behind him at $13,501,387 and Tim McGraw only a few thousand behind her with $13,494,737. Rascal Flatts made it into the Top 20, coming in at No. 16 with $11,958,021.

Other country artists on Billboard's list of top earners include Toby Keith and Lady Antebellum making more than $9 million each. Retired duo Brooks & Dunn went out with a bang last year, making more than $8.5 million, while touring partners George Strait and Reba McEntire both adding over $7 million to their bank accounts. Finally, Sugarland wraps up the list, coming in at No. 39 with more than $4 million earned.

Tim McGraw was also recognized by Billboard for as having one of the top tours of 2010, while Taylor earned the honor of 'Top Package' for the Billboard Touring Awards. See her international concert schedule here.
