They are well conceived and convey a lot without dialogues, that Dargha song, Roshni se, even the Charlie Chaplin one. They indicate what's coming up as well as their current state.
Tho' i hated the 1942 song, when RNj did the clown act, imo,it was indicate of him he becoming an idiot in the near future. Guess, with all the feeding shown by RGD in this song, i think, she is going to be the anchor in the search & rescue mission for RM.
As long as their choice of song aligns with my taste and they show a proper progression towards to the song & dance, am cool.
It's the randomness of shoving a dance & song that annoys me.
I hope we get a scene of RM & RNJ before she goes missing. may be they'll show she went before they got everything back and commotion broke out.
