From my thought i do accept coach K

From my thought i do accept coach Kim decision for Nan
+Cuz i really like 'Taitanium' Look Peach do make it good but not so great
she does hit the note with powerful voice but if u listen to the original it's not just a powerful song but it's more deep than that, so i think this song is too much for her.
+But Nan this stage was the less acting stage of her, she looks so calm but
into the inner of the song as it should be. At first i think Look Peach will go on sure.
