Lyrics: "Sache Que Je" translates to "Know That I." The song is written and performed by the French singer-songwriter Jean-Jacques Goldman. It was released in 1985 as a part of his album "Non Homologué." The song explores the complexities and nuances of love and the power of words. It suggests that love cannot always be accurately expressed through words alone, as there are shadows and traces of time within the expression "I love you." It implies that love goes beyond mere words and can also include contracts and obligations. Goldman questions the true meaning and effectiveness of words, stating that love has its own language that may not necessarily be served through words. He compares it to a hostage situation, where one needs specific phrases and words like a seal on a parchment to validate their feelings. Furthermore, the song emphasizes that expressing love goes beyond just words and involves sacrificing oneself and being completely devoted to the person you love. The lyrics state that in saying "I love you," one is also saying that they are willing to die for the other person, to let go of the world and its poems, and only focus on the love between them. It also suggests that saying "I love you" is not a straightforward affirmation but can also raise a question in return: "And do you love me too?" This implies that love is interconnected and reciprocal, and just saying the words is not enough to guarantee mutual feelings. Overall, "Sache Que Je" is a heartfelt exploration of the complexities and depth of love, highlighting that it goes beyond words and requires genuine commitment and understanding between two individuals.
