What "Girl Crush" controversy? After reports surfaced that some radio stations were boycotting Little Big Town's latest single while others were saying that those reports were unfounded, the quartet's tune has notched 2015's best single week of sales for a country song.

Aided by LBT's performance of the gold-certified tune at the 2015 ACM Awards, "Girl Crush" sold more than 97,000 units in the days just before and after the awards show; on the day of the ACM Awards alone (April 19), the song sold more than 30,000 units. The ACMs performance also became the most Shazamed moment of the entire awards show broadcast.

"Girl Crush," from Little Big Town's 2014 Pain Killer album, was the most-added song at country radio when it was released last year. The tune was written by Lori McKenna, Hillary Lindsey and Liz Rose, and all four LBT members knew from their first listen that the song was meant for them.

“I knew as soon as I heard the hook of the first chorus that we had to have this song,” Fairchild recalls. “I’d never heard a jealousy song written like this. It’s definitely one of the best songs I’ve ever heard, and to get to sing it every night is a gift.

“It could be a bit of a game changer on country radio right now,” she adds. “There are not many women on the radio and not many ballads with that kind of lyrical content."

The reigning ACM Vocal Group of the Year will have plenty of chances to perform the song live as they cross the country on their 2015 Pain Killer Tour, which includes a stop at the iHeartRadio Country Festival in May. All of their upcoming dates are available on their website.
