This is a really cool bollywood song by Dil Se (i think xD), one of my fav I hope you all like it. I wonder how they filmed the whole thing while they're dancing on the train... I wish i had more information on the video if anyone does please post it.
EDIT: Apparently Dil Se is the name of the movie, also if you REALLY want to know more about this movie I suggest you read the comments xD. Theres alot of information down there
