song selection/???????????????????

i want 2 say that when i read this song selection i fail to understand whyis it needed.these singers who have been called better then II nd FG shud be able to sing any song with same ease.frm FG give arijit kirti nd rex any song,they will show u how 2 sing that the best.frm II,leaving amit tondon nd ravinder,almost all were very gud,nd specially amit sana,give him any song,he will make it xceellent,even if u heard it or not.so how's the question of song selection.
