Question: This song that was released on August 30, 2009, was the fourth single off of the album for what singer who co-produced that album with Nathan Chapman?
Context: "State of Grace" is a song by American singer-songwriter Taylor Swift from her fourth studio album "Red" (2012).  It was released to the iTunes Store on October 16, 2012, in the United States by Big Machine Records as the fourth and final promotional single from the album.  It was the only promotional single from the album that was not re-issued as an official single, as "Begin Again", "Red", and "I Knew You Were Trouble", were all later re-issued as official singles.  The song was written by Swift and produced by Nathan Chapman and Swift.  Musically, the song is a departure from Swift's typical country pop, using influences of alternative rock while being compared to bands such as U2, Muse and The Cranberries.  The song has received immense praise from music critics, who have complimented its broader sound in comparison with Swift's previous material. "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. "Change" is a song performed by American singer-songwriter Taylor Swift.  Swift self-penned the song and co-produced it alongside Nathan Chapman.  The song was released on August 8, 2008, with all proceeds being donated to the United States Olympic team.  "Change" was written about Swift's hopes and aspirations in regards to succeeding, although being signed to the smallest record label in Nashville, Tennessee.  The track was later chosen as one of the themes for the 2008 Summer Olympics and was included on the "AT&T Team USA Soundtrack", which was released August 7, 2008.  The song was later included on Swift's second studio album "Fearless", which was released in November 2008.  "Change" is musically pop rock and uses divergent string instruments.  Lyrically, it speaks of overcoming obstacles and achieving victory. 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. "Today Is Your Day" is a song by the Canadian singer-songwriter Shania Twain.  It was self-penned by Twain and co-produced by David Foster and Nathan Chapman.  The song was released on June 12, 2011 by Mercury Nashville Records, as a promotional single to accompany the documentary television series "Why Not?  with Shania Twain" (2011).  The song marked Twain's first song release in over six years and actually even the only song release of her own within a timespan of twelve years.  Twain wrote the track for self-inspiration, during the development of "Why Not?  with Shania Twain".  To her, "Today Is Your Day" became the theme song for the series, expressing the purpose behind it via music.  Despite feeling apprehensive, Twain decided to record the track, which induced her to create her forthcoming fifth studio album.  The track is midtempo ballad in the country pop genre.  Lyrically, "Today Is Your Day" regards personal upliftment.  "Today Is Your Day" is Twain's first piece of music to have had no involvement with now ex-husband Robert John "Mutt" Lange in 16 years and only her second self-penned song, the first one being "Leaving Is The Only Way Out" on the album "The Woman In Me" "Fifteen" is a country pop song performed by American singer-songwriter Taylor Swift.  Swift self-penned the song and co-produced it along with Nathan Chapman.  "Fifteen" was released on August 30, 2009 by Big Machine Records, as the fourth single from Swift's second studio album, "Fearless" (2008).  The song was inspired by Swift's freshman year of high school at Hendersonville High School, where she first encountered heartbreak, along with her best friend Abigail Anderson.  After writing it, Swift asked Anderson for authorization to record the song (due to personal references in the song); Anderson affirmed and it was ultimately included on "Fearless".  "Fifteen" is a ballad, which has Swift reminiscing on events that occurred to her and her best friend at the age of 15 and cautioning teenagers to not fall in love easily.
