The best band of world is one direction. I am very sad about zayn malik who left the group. He gives lots of things to one direction. The song they sing is excellent and the style of Harry Style is superb. My whole family is fan of one direction. My best song of one direction is "Story of my life". The singers of the one direction is not only a singer, they are a best actor also. No one can take the place of one direction because they are only one piece in world.
