Taylor sings with heart

The music industry is never short of teen pop stars with wonderful looks, but it doesn’t often find one like US singer Taylor Swift. “Beneath Taylor Swift’s not-a-girl, not-yet-a-woman sweetness hides a very skillful songwriting technique (技巧),” writes Leah Greenblatt with Entertainment Weekly.

Songwriting, the country singer explains, is “how I deal with problems. I am used to writing about things that really influences me most.” So in her songs, there is always something true and honest. They seem like stories from a diary. And that certainly helps Swift attract her audience.

She’s sold more than 13 million copies worldwide of her first two albums, 2006’s self-titled debut (首张专辑) and 2008’s Fearless. She’s the youngest artist ever to be named Artist of the Year at the American Music Awards. Not surprisingly, there were great expectations for her third album, Speak Now, which came out late last month, where she again returned to her own life for material. The 14 songs “are all about the last two years... when life was a little bit bigger and crazier,” says Swift. “So I’ve written about the lessons and confusion and heartbreak and all the different things that go along with being 18, 19 and 20.”
