The song "L'ancien" by Heuss L'Enfoiré is about the advice and guidance he receives from an older and more experienced person. The older person advises him to invest in real estate in Africa and Europe, but Heuss is more focused on his music career. The older person also warns him about the dangers of success and reminds him to stay true to his roots and keep collecting money. Heuss reflects on his past struggles with drugs and prison, but acknowledges his current success and the people who have supported him along the way. The song is a tribute to the wisdom and guidance of older generations and the importance of staying true to oneself in the pursuit of success.
