Carrie Underwood is back up at top with her latest hit single 'Good Girl' -- not that that's anything new for her. This week, the song tops both the Mediabase / Country Aircheck and Billboard country singles charts.

The tune was the lead single from Underwood's newly released 'Blown Away' album -- her first full length project in three years. And like most of the chart-topping singles she's had throughout her career, Underwood co-wrote the tune, this time with hit songwriters Ashley Gorley and Chris DeStefano. The song was an instant hit at country radio and with the singer's fans, who have obviously missed her powerful pipes coming through their speakers.

"I love Carrie’s voice being exposed the way it is in this song, sometimes singing with just drums or hand claps, and even acapella at the end of the song," Gorley told Taste of Country earlier this year. "She has more power and control with her voice than anyone I’ve ever been in a room with. I don’t think anybody else could sing that song. We had a blast working on it!"

Coming in behind Underwood on the charts this week are songs by the Zac Brown Band ('No Hurry'), Eric Church ('Springsteen'), Luke Bryan ('Drunk on You') and Tim McGraw ('Better Than I Used to Be').
