Question: On what date was the Taylor Swift studio album which had "Back to December" on it released?
Context: Speak Now is the third studio album by American singer-songwriter Taylor Swift.  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", "Speak Now" expands on the country pop style of her previous work, and features lyrical themes including love, romance and heartbreak. Fearless is the second studio album by the American singer-songwriter Taylor Swift.  The album was released on November 11, 2008, by Big Machine Records.  As with her first album, "Taylor Swift", Swift wrote or co-wrote all thirteen tracks on "Fearless".  Most of the songs were written as the singer promoted her first album as the opening act for numerous country artists.  Due to the unavailability of collaborators on the road, eight songs were written by Swift.  Other songs were co-written with Liz Rose, Hillary Lindsey, Colbie Caillat, and John Rich.  Swift also made her debut as a record producer, co-producing all songs on the album with Nathan Chapman. Red is the fourth studio album by American singer-songwriter Taylor Swift.  It was released on October 22, 2012, by Big Machine Records, as the follow-up to her third studio album, "Speak Now".  The album title was inspired by the "semi-toxic relationships" that Swift experienced during the process of conceiving this album, which Swift described the emotions she felt as "red emotions" due to their intense and tumultuous nature.  "Red" touches on Swift's signature themes of love and heartbreak, however, from a more mature perspective while exploring other themes such as fame and the pressure of being in the limelight.  The album features collaborations with producers and guest artists such as Gary Lightbody of Snow Patrol and Ed Sheeran and is noted for Swift's experimentation with new musical genres.  Swift completed The Red Tour in support of the album on June 12, 2014, which became the highest-grossing tour of all time by a country artist, grossing over $150 million. "Fearless" is a country pop song performed by American singer-songwriter Taylor Swift.  The song was co-written by Swift in collaboration with Liz Rose and Hillary Lindsey and produced by Nathan Chapman and Swift.  "Fearless" was released on January 3, 2010 by Big Machine Records as the fifth and final single from Swift's second studio album of the same name (2008).  Swift composed the song while traveling on tour to promote her eponymous debut album, "Taylor Swift" (2006).  She wrote "Fearless" in regard to the fearlessness of falling in love and eventually titled her second studio album after the song.  Musically, it contains qualities commonly found in country pop music and, lyrically, is about a perfect first date. "Our Song" is a country song performed by American singer-songwriter Taylor Swift.  The song was written by Swift and produced by Nathan Chapman.  It was released on September 9, 2007 by Big Machine Records as the third single from Swift's eponymous debut album, "Taylor Swift" (2006).  Swift solely composed "Our Song" for the talent show of her freshman year in high school, about a boyfriend who she did not have a song with.  It was included on "Taylor Swift" as she recalled its popularity with her classmates.  The uptempo track is musically driven mainly by banjo and lyrically describes a young couple who use the events in their lives in place of a regular song. "Picture to Burn" is a song recorded by American singer-songwriter Taylor Swift.  It was co-written by Swift and Liz Rose, and produced by Nathan Chapman.  It was released on February 3, 2008 by Big Machine Records as the fourth single from Swift's eponymous studio album, "Taylor Swift" (2006).  It was inspired by the narcissistic and cocky nature of her former high school classmate and ex-boyfriend Jordan Alford with whom Swift never established a formal relationship.  In retrospect, Swift has stated that she has evolved on a personal level and as a songwriter, claiming she processed emotions differently since "Picture to Burn".  The song was chosen as a single based on the audience's reaction to it in concert.  Musically, the track is of the country rock genre with prominent usage of guitar, banjo, and drums.  The lyrics concern setting fire to photographs of a former boyfriend. Taylor Swift is the debut studio album by American singer-songwriter Taylor Swift, released on October 24, 2006, by Big Machine Records.  Swift was 16 years old at the time of the album's release and wrote its songs during her freshman year of high school.  Swift has writing credits on all of the album's songs, including those co-written with Liz Rose.  Swift experimented with several producers, ultimately choosing Nathan Chapman, who had produced her demo album.  Musically, the album is country music styled, and lyrically it speaks of romantic relationships, a couple of which Swift wrote from observing relationships before being in one.  Lyrics also touch on Swift's personal struggles in high school. "Back to December" is a song written and recorded by American singer/songwriter Taylor Swift for her third studio album "Speak Now" (2010).  The song was sent to country radio in the United States on November 15, 2010, as the second single from "Speak Now".  According to Swift, "Back to December" is the first time she ever apologizes to someone in a song.  Critics speculate that the song is about Taylor Lautner, Swift's ex-boyfriend, which was later acknowledged by Lautner.  "Back to December" is considered an orchestral country pop ballad and its lyrics are a remorseful plea for forgiveness for breaking up with a former lover. "Teardrops on My Guitar" is a song by American singer-songwriter Taylor Swift.  The song was co-written by Swift, alongside Liz Rose and produced by Nathan Chapman with Swift's aid.  "Teardrops on My Guitar" was released on February 19, 2007 by Big Machine Records, as the second single from Swift's eponymous debut album (2006).  The song was later included on the international release of Swift's second studio album, "Fearless" (2008), and released as the second pop single from the album in the United Kingdom.  It was inspired by Swift's experience with Drew Hardwick, a classmate of hers for whom she had feelings.  He was completely unaware and continually spoke about his girlfriend to Swift, something she pretended to be endeared by.  Years afterwards, Hardwick appeared at Swift's house, but Swift rejected him.  Musically, the track is soft and is primarily guided by a gentle acoustic guitar.  Critics have queried the song's classification as country music, with those in agreement (such as Grady Smith of "Rolling Stone") citing the themes and narrative style as country-influenced and those opposed (such as Roger Holland of "PopMatters") indicating the pop music production and instrumentation lack traditional country elements.
