Hikki was never the best live singer since the beginning. I remember I heard First Love on music station and thought it wasn't as good as the studio recording

(and I wasn't really a hikki fan until 3 months after - the release of ATY). I think the last 5 songs she made tho (single collection vol. 2) were in her range, so actually she did really good on those songs. And after hearing Wild Life, I think her voice was getting better actually. (Yeah I repeated my post again and again lol. Forgive me).
So do we want less attractive songs from hikki but she could comfortably sing them, or should she go for wild songs, like BLUE?
