Little Big Town's "Girl Crush" is a song that inspired other artists. Song No. 6 on this list of the Top Country Songs of the Century reminded anyone feeling held down in a very cautious genre that it's alright to be different.

Thompson Square were among the artists to choose "Girl Crush" as one of their top songs of the 21st century. Keifer Thompson says he appreciates the courage it took for Little Big Town to once again redefine themselves with a song that is truly twisted.

“There's room for everybody,” Thompson says of the lesson he learned from the song. “If everything sounds the same, it just kind of shrivels up and dies.”

This Top 5 hit won CMA and Grammy Awards and made several Best Songs of 2015 lists. Suddenly, Little Big Town were performing on every major television awards show, but they found ways to reinvent their performance for most of those appearances. Another singer could not have done the song justice. This is Karen Fairchild's moment — a song that fans will line up and wait for at every Little Big Town concert until the foursome call it quits.
