80. Taylor Swift
It was inevitable that Taylor Swift would leave country music behind for pop – her superstar quality could not be contained by just one genre. As a teenager writing her own songs, Swift – born in Pennsylvania, groomed in Nashville – impacted country radio before she was even 18, with "Tim McGraw" a Top 10 hit, and "Our Song" her first country Number One in 2007. By the time she'd invoked the wrath of Kanye West at the 2009 VMAs, she was already playing to a different tune than her peers, and subsequent LPs Fearless and Red led to greater notoriety. Still, her conscious uncoupling from the genre that established her ahead of 2014's smash 1989 left some wishing she kept one foot in country. "Love you, mean it," Swift said in a 2014 Rolling Stone cover story, "but this is how it's going to be." J.G.
