It was written by Perry, Christopher "Tricky" Stewart, Monte Neuble, and Matt Thiessen, and produced by Stewart and Kuk Harrell.  Musically, "Dressin' Up" incorporates the styles of electro and dance-rock, along with a prominent electronic dance production.  Lyrically, the song speaks of dressing up in different outfits for a lover, and contains multiple innuendos.  "Dressin' Up" garnered mixed reviews from critics, some of whom complimented its "fun" sound, while others denounced it as being too similar to Perry's other works.  Upon the release of "Teenage Dream: The Complete Confection", the song charted on the UK Singles Chart at number 109. "Long Shot" is a song by American singer Kelly Clarkson, from her fourth studio album, "All I Ever Wanted" (2009).  Written by Katy Perry, Glen Ballard, and Matt Thiessen, it was originally recorded by Perry (along with the single "I Do Not Hook Up") for an unreleased album and was later re-recorded by Clarkson.  It is a pop song about taking a chance on pursuing a flawed relationship in spite of it being a "long shot." Matthew Arnold "Matt" Thiessen (born August 12, 1980) is a Canadian-American musician, singer and songwriter known for being co-founder, lead singer, guitarist, pianist, and primary songwriter for the Christian rock band Relient K.  With Relient K, he has released eight full-length albums, including three that were certified Gold, and three that peaked in the top twenty on the "Billboard" 200.  Outside of his work with Relient K, Thiessen maintains a low-profile side project called Matthew Thiessen and the Earthquakes.  In 2009, he co-produced and collaborated on Owl City's album "Ocean Eyes". "My Girlfriend" is a song by the Christian rock band Relient K, released on their self-titled first album.  The song originally appeared as "Marilyn Manson Ate My Girlfriend" on the band's demo album, "All Work and No Play".  The song is about Marilyn Manson eating Matt Thiessen's girlfriend.  Thiessen wrote this song when he was 15 years old.  Thiessen has said that he wrote it because of a female friend, who lived eight hours away in Pennsylvania, who he would talk to about many things including spiritual matters such as where God was taking them in the future.  His friend would later turn from Christian music to Nine Inch Nails and Marilyn Manson.  In an interview with CCM Magazine Thiessen stated "through this she changed her lifestyle [and] what she believed in."  His friend would later be expelled from school and would be kicked out of her house and sent to a youth detention center.  Thiessen would later state "She felt that Christianity was stupid and just this big hypocrisy.  Being young and impressionable, I just wrote this little, stupid song, but that was the way I dealt with it—writing this song about how she got so consumed by Marilyn Manson." "Fireflies" is the debut single from American electronica project Owl City's album "Ocean Eyes".  Relient K vocalist Matt Thiessen is featured as a guest vocalist on the song.  Adam Young described the song as "a little song about bugs and not being able to fall asleep at night."  The song is built around a "bleepy" synthline and includes lyrics about insomnia, fireflies and summer. "Rebuild" is a song written by Jon Foreman of Switchfoot and Matt Thiessen of Relient K.  The song was written in conjunction with the bands' 2007 Appetite for Construction Tour, featuring members from all three bands on tour, Switchfoot, Relient K, and Ruth.  Thiessen sang second vocals, and Dustin Ruth of Ruth played harmonica.
