A true singer doesn't have a formula. Some people would argue a true singer is someone like Celine Dion or Mariah Carey or Whitney Houston, who have a wide range of hitting notes. BoA doesn't even get close to them if you talk about that kind of singing. However, what makes music is not just some rigid formula. a true singer doesn't exist. For instance, there are many people who despise CD, MC or WHouston. Some people hate BoA. There's no artist enjoyed by every and each human being, because music refer to personal tastes. ayu might not be perfect when it comes to singing, but she still IS a singer. BoA is no more of a singer than ayu. ayu at least compose some songs and write all her lyrics, which shows she puts effort on the music, BoA puts more effort on her coreography and performances.
