[Ayumiko]

Whether ayu decided on the title in the first place or not, in the end she has the final say imo. I remember I read somewhere that Max Matsuura said ayu is really the one who produced her work even though he gets credit for it...so it might be why her tours now is 'all produced by ayumi hamasaki'. I'm sure ayu still have orders to follow...like having to do a tour and produce an album each year, etc. but in terms of creative control, I think she has full control over it. For some stuff she probably lets her staff create it and she'll approve or make changes in the end.
