Background
"What You Don't Know" was written by Swedish songwriters Mattias Lindblom and Anders Wollbeck along with American musician Billy Mann, while production was overseen by frequent Monrose contributors Christian Ballard, Tim Hawes, Pete Kirtley, Obi Mhondera, and Andrew Murray for British production teams Jiant and Snowflake.

Critical reception
"What You Don't Know" earned largely positive reviews. Julia Dörfler from laut.de wrote that the song "turns out to be a ballad in which the three stars can shine with their voices. The pure acoustic instrumentation makes the melancholic track stand out from the rest of the album." Kronen Zeitung found that with the song "Monrose show the other side of their hit album Strictly Physical for the first time. The soulful heart-pain ballad lives only through the singing skills of the three girls." Letmeentertainyou.de felt that the ballad suffered from its "cold plastic production."

Music video
A music video for "What You Don't Know," directed by Markus Gerwinat and produced by Q-Filmproduktion, was shot on 13 November 2007 in Hamburg, Germany, and world premiered on November 23 on German music network VIVA's show Viva Live!. Actress Toula Savvidou plays one of the characters in the visuals.

At the beginning of the video, a woman (Savvidou) leaves her bed while her male partner looks on. She seemingly ignores him. The three women of Monrose are then seen over an intersection standing and singing between shots. Bahar Kizil is seen throughout the video along with her reflection, walking streets, while Senna Gammour is seen in the backseat of a car. Mandy Capristo is shown alone. The woman of the story lives her life while the man follows, and she continues in not noticing him. By the end of the video, it is revealed that he is dead, and was killed in an automobile accident. She loved him then and still. His body fades as he learns the truth, and the video comes to a close.
