The album containing songs solely written by Taylor Swift was Speak Now. Released in 2010, it was Swift's third studio album and represented a deliberate decision to write every song herself.
Swift had co-written many songs on her earlier albums, including Fearless, but wrote the original standard-edition tracks on Speak Now without co-writers. The album grew from her country-pop foundations while expanding into rock, pop, and highly narrative songwriting. Songs such as “Mine,” “Back to December,” “Mean,” and “Enchanted” helped make it one of the defining records of her early career.
The title reflects the album's central idea of saying what you feel before the moment passes. Its songs draw on romance, regret, public criticism, and the pressure of growing up in the spotlight. Swift was around 20 when the album was released, although some songs had been written earlier.
A small qualification causes occasional confusion: the deluxe edition included “If This Was a Movie,” which has a co-writing credit for Martin Johnson. The standard album is the version normally meant by the quiz question, and it is widely described as Swift's entirely self-written album.
