Rascal Flatts has just joined a very exclusive group. Their 2006 single “Life Is A Highway” just crossed the billion streams plateau on Spotify, making the song one of only 17 country songs in the Spotify Billions Club. The song was originally a rock and pop hit for Canadian musician Tom Cochrane in 1992; Flatts covered it for the soundtrack for the Pixar film “Cars,” where it became not only a country but a pop hit as well. Over 1,300 songs have reached the one billion mark on Spotify, but oddly, only 17 of these are country. With “Life Is A Highway” the latest to cross that threshold, the song now becomes the oldest country song to do so.
