IMO the point about finishing touch that abhijit da and later shaan too brought up was something noteworthy !
In all honesty i did feel yashodhan lacked the finishing touch as abhijeet said and yatharth is a master of that as shaan observed . I guess the finishing touch really takes the singing from good to kinda exceptional level.
However what i didn't get was why didn't they talk about the finishing touch when swarit was singing "main aisa kyon hoon". I thought he lacked it too.😕
