Garth Brooks' comeback has certainly been a success. The country music superstar has landed at the top of Forbes' 2015 list of the highest-paid country acts.

With more than $90 million in revenue during the last year, thanks to the record-breaking sold-out shows on Brooks' World Tour, the Oklahoma native also earned the highest single-year revenue that Forbes has ever recorded for a country artist.

Toby Keith, who came in at No. 10 last year on Forbes' list of the highest-paid musicians, came in a distant second on this new list, having earned $53 million. He is followed by Jason Aldean in third ($43.5 million), Luke Bryan in fourth ($42.5 million) and Kenny Chesney rounding out the Top 5 ($42 million).

Earlier this month, Brooks came in at No. 6 on Forbes‘ list of the world’s highest-paid celebrities. But while the singer-songwriter is enjoying another surge in his career, he says that the money isn't how he measures his success.

“For me, I don’t care about the dollar bill bottom line, I care about the memories of, did I have fun there? Did we get to do stuff as a crew there, as a band there?” he tells The Boot of picking stops for his World Tour. “You betcha, we’re going back to all the fun places.”

Other artists on Forbes' 2015 list of the highest-paid country stars include Tim McGraw, Florida Georgia Line, Miranda Lambert and Blake Shelton (who were tied), Keith Urban and Eric Church. See the complete list on Forbes' website.

Brooks' World Tour, which also features his wife Trisha Yearwood, will kick off its second leg beginning on Sept. 17 in Dallas, Texas.
