Also the song is to promote the film as it will be on the end credits, the promotion is obviously there. It has clocked 20M views in a day.

No one can hide from the fact that without a good screenplay it is difficult for any film to run today so the song just adds up to the hype and nothing more. Siddharth Anand has made Bang Bang, WAR in this genre and it has done really well. I believe he has an eye for action so action scenes will be fantastic. If the screenplay is good the film will do very good.

The songs may not be like the old bollywood classics, but has been very popular and will definitely help in keeping the buzz which as I said is the soul purpose of these songs. Not the longevity that redditers are expecting.
