People like Werra and Koffi are now not really good singers ,
but they know how to be big stars
I've seen Koffi live enough times to conform he's an authentic good singer. There may be songs here and there he struggles with but definitely not a faux chanteur.
Werra maybe a dodgy singer, but he's been very intelligent and lucrative from the early Wenge days to now. His success is no fluke. One only becomes an artiste confirmé after putting out consistently good singles/albums/concerts and having a strong fanbase.
