“Superman” is a love song and the seventeenth song on Taylor Swift’s deluxe which is also the third studio album by the American singer-songwriter. It was released on October 25, 2010, by Big Machine Records. Production for the album took place during 2009 to 2010 at several recording studios, and was handled by Swift and Nathan Chapman.
Written entirely by Swift as the follow-up to Fearless, and described as a loose concept album about confessions, Speak Now expands on the country pop style of her previous work, and features lyrical themes including love, romance, and heartbreak. Source
