"Mine" is a song written and recorded by American country pop artist Taylor Swift. It is the lead single and opening track from her third studio album, Speak Now, and the eleventh single release of her career. The song was released on August 4, 2010, two weeks ahead of the planned August 16 release, due to its online leak. It has sold 1,109,000. copies. The track has also been added to Radio 1's A-Playlist in the United Kingdom.The song has been reviewed positively by music critics. KILT-FM describes "Mine" as "an uptempo song that’s unmistakably Taylor," comparing its theme to "Love Story" but saying that however it had "a much more realistic look" than the latter. The review also said the song showed "growth" and "maturity," and has a "big chorus." Giving it three-and-a-half stars out of five, Bobby Peacock of Roughstock thought that the song was similar in sound to her previous works, but added that it fit well into "her own musical niche." Blake Boldt of The 9513 gave the song a thumbs-down, saying that it seemed more mature than her previous work and calling it a "mishmash of ideas bolted together by a terrific power-pop chorus that will stick in your brain," but adding that the line "You made a rebel of a careless man’s careful daughter" did not have a "payoff."
