If you wish to check Stings myspace, you'll find, nowadays, he categorizes himself as "acoustic, pop, rock"; and, whilst changes in style may have been made here by the likes of Sting, pop and rock originate in America.
I studied the works of several social anthropologists, Tim; although I recall Adelaide having close links with the "Manchester School".
Also, for what it's worth, I'm pleased Sting has recently turned his hand to English folk and Renaissance music, even though I'd rather hear, e.g., Emily Portman sing "The Snow it Melts the Soonest".
