I'm gonna write about them because I love most of their songs. My favourite songs are History, Perfect, What Makes You Beatiful, Drag Me Down, Live While We're Young, End of the Day and Little Things.
At the beginning, they were five people; Harry Styles, Liam Payne, Niall Horan, Zayn Malik and Louis Tomlinson. Nevertheless on 25 March, 2015 Zayn Malik left the band, so now the band is composed by four members.
Each one went to a TV programme called The X Factor. Simon Cowell suggested they form a band and they did it. Now they are very famous and they have done four worldwide tours.
They have five albums: Up All Night, Take Me Home, Midnight Memories, Four and the latest is Made in the AM. Every year, they put on sale one from 2011 to 2015.
Here there are their official website and two of their official videos:
