The song "Formidable" by Stromae is about the ups and downs of relationships and experiences between people. The singer reflects on different scenarios and relationships, comparing them to a "formidable" - a powerful and positive - situation he once had that was ultimately not meant to last. The song explores the idea of how ultimately, no matter how amazing a relationship may be, it won't remain that way forever - and that no matter how minable - weak and negative - a situation may feel, you can find strength and positivity in remembering how good it once seemed.
