I think especially in this context where she has to "prove something" to mbilia bel,that koffi should put her on some odemba music,the very keyboard oriented tchatcho sound sometimes is not "taken seriously enough"
put her on some strong odemba with proper chorus and guitar,she'll already look more "serious" than the tchatcho format where it looks "too familiar" to people now she has about 50 songs of the type already
especially as she really sings well,it will highlight even more her talent in my opinion than the "soft" tchatcho
