Making the shift from teen sensation to mature artist can be tough, but on her second album, Fearless, an 18-year-old Taylor Swift did it with style. The songs ring out with angst and delight in equal measure. Guitars chime and beats bounce as Swift sails through the title track, “Hey Stephen,” and “You Belong With Me” with boundless joy. These moments glow all the more alongside thoughtful tunes like “Fifteen” (a knowing glance back at high school) and “White Horse” (a snapshot of lost innocence).
