The guys in Florida Georgia Line are celebrating yet another milestone in the chart life of their mega-hit song 'Cruise.' The career-making hit single has now spent a total of 17 weeks in the No. 1 position on Billboard's Hot Country Songs chart -- the longest any song has held that spot in 50 years.

According to Roughstock, Leroy Van Dyke's 'Walk on By' spent 19 weeks at No. 1 in 1962, and Eddy Arnold, Hank Snow and Webb Pierce all had songs that spent a total of 21 weeks at the top of the charts during their careers. That means if 'Cruise' can hold onto the top spot for five more weeks, it would become the longest-charting No. 1 country single in Billboard history.

Incredibly, the duo's first full-length studio album, 'Here's to the Good Times,' was just released in December of 2012. 'Cruise' was the first single from that collection, and its success has been bolstered considerably by a remix featuring rapper Nelly. The second single from the album, 'Get Your Shine On,' also spent some time at No. 1 in May. The album's third single, 'Round Here,' was released in June.

Florida Georgia Line are currently on the road with Thompson Square and Luke Bryan as part of Bryan's Dirt Road Diaries tour.
