I find in America, actually, I actually prefer it because it's all about energy. It's all about making everyone feel happy and smiling. In the U.K. sometimes people are a bit too concerned about, 'Did you play that track? Did you play that track?' It's not so much about the music in the U.K.
There's benefits of having established artists on the record, Liam Payne on 'Polaroid' for example. If you look at that song you have Lennon Stella, who's an up-and-coming artist, so there's a balance on there because I still want people to focus on the song just as much as Liam being an amazing superstar.
