Why was Mouna not a duet of Lacoste & Shella Mputu who were credited both as the songwriter of the song ? Because Shella sung almost solo in that song. Didn't Adolphe like Lacoste anymore in the band or what ? Because in the same album the song Inspiration was on Disc 2 as 5th song, while was the number 2 of Wenge Tonya Tonya.
