+`White Horse" is a single by Taylor Swift (pictured) from her second studio album, Fearless. A country pop song, the ballad is driven by a finger-picked guitar and includes piano and cello accents. The lyrics incorporate fairy-tale imagery of princesses and white horses: a narrator is heartbroken that her boyfriend is not an ideal figure and leaves her town to find another partner. Big Machine Records released the track to US country radio on December 8, 2008. Music critics lauded "White Horse" for its somber production and portrayal of heartbreak, but some found the lyrics uncreative. In 2010, the song won Grammy Awards for Best Country Song and Best Female Country Vocal Performance. In the US, the single peaked at number 13 on the Billboard Hot 100 and number 2 on the Hot Country Songs chart. It was also certified in the US, Australia and Canada. Following a 2019 dispute regarding the ownership of Swift's back catalog, she re-recorded the song for her album Fearless (Taylor's Version).`
