Dolly Parton has spoken out about the political background of her new song, ‘World on Fire’.In a new interview with Vulture, the country legend was responding to superlatives, and named ‘World On Fire’ as the song that “best embodies your own mythology”. ‘World On Fire’ appears on her new album ‘Rockstar’, which became her highest-charting album at number 3 and gaining four stars from NME.“I write a lot of uplifting songs, but I think ‘World on Fire’ makes a statement because people often say, ‘Oh, I didn’t know you’re political’,” she said.
