In 2003 it's finally time for Ruth Kotto to release her first solo album entitled 'Dame de Coeur'.
She says the following about the choice for this title in an interview with Cameroon-Info.net:
(...) I decided to give the title 'Dame de Coeur' to this album to express all the feelings that animated me at some point or other of its realization. The album as a whole is only a sum of messages, joys, fears and apprehensions that I wanted to share with music lovers. So I realized that I had a lot to give, a lot of massages to share that we had to find a title that could be a sort of summary of all the feelings that I feel through the twelve titles that make up the album. Moreover, as a woman, I could not remain long insensitive to the problems that women encounter in their daily lives. So I seized the opportunity here to express my solidarity to all these battered women in their homes, to all those single women to suffer the wordt attrocities. I offer them my heart. That's the only thing I could do for the moment (...).
In addition, the title Dame de Coeur also refers to a kind of rose that bears this name. The album was quite successful, and she has a few hits, notably Ton Pied Mon Pied.
The years after that, it becomes quiet around Ruth, family life must have kept her busy, she gave birth to two children. But in 2009 she is back with the single Nyambé in which she tells a beautiful story about the lonelyness that can prevail in some people in difficult moments of life.
