Mirotic is TVXQ's fourth South Korean studio album, released on September 26, 2008. The album had been in production since 2007, but the title was not decided upon until January 2008. TVXQ members Xiah, Junsu and Max Changmin participated directly in the making of the album, penning the lyrics for "노을.. 바라보다 (Picture of You)" and "Love in the Ice", respectively. In addition, members Hero Jaejoong and Micky Yoochun composed and wrote the lyrics to "사랑아 울지마 (Don't Cry My Lover)" and "사랑 안녕 사랑 (Love Bye Love)", respectively, for version C of the album. Three days after its release, Mirotic became the best selling album of the year. On November 15, 2008, the album won the album of the year award at the 2008 MKMF Korean Music Festival awards.

The choreography of "주문-Mirotic," the title track of the album, was done in a collaboration between Korean choreographers and Kenny Wormald, who had also worked with pop stars Justin Timberlake, Chris Brown and Christina Aguilera.^[1] The song features a "reverse beat" track, meaning that the bass beat is either a half beat or a whole beat late in coming into a new phrase. While in most genres of music, the bass note comes in directly on the first beat of the measure in setting the chord of the phrase, reverse beat songs alter this usual method. In doing so, the reverse beat genre is said to have an effect of "growing on" the listener, having an addictive sound.

"Mirotic" is a newly coined term, created by Hero Jaejoong, that combines the Korean MIRO (미로), meaning "maze", and the English suffix "-tic".

The title song was composed by the Danish producers, Remee, Lucas Secon and Thomas Troelsen. The German singer, Sarah Connor, also bought the copyright to the song (not specified when). Despite the fact that the two original songs were the same composed piece, they have musical differences (TVXQ's version has a rap and multi-layered harmonies while Connor's has a bridge; the melodies in the chorus also differ).
