Hi. My favorite band is one direction the Irish boy band and I listen to them ALL day.
Oh i see. Which of their song is the most popular? 
Yes. What Makes You Beautiful is perhaps the one most popular song, but they have many other good songs
What genre of music do they sing? 
They sing a variety of music but pop music is probably their focal point. They have won six Brit Award because of this genre
They must be very incredible band. Where are they from?
Yep, I agree. They are an English band, based in London. But they travel all around the world. 
Have they ever been to the US before. I am looking forward to go for one of their concerts
