"We write from personal experience, and I think everyone does, so it would be hypocritical of us to be like, 'Oh you can't write about us,'" Styles said. "And she's really good, so they're good songs. So I'm really lucky in that sense."

Perhaps, if it was a bad song, Styles would be a lot more upset. Speaking of bad songs, the guys of 1D did admit there's a few songs on their debut that they're not too fond of, including "Stand Up" and "What Makes You Beautiful." Yes, one of their biggest hits.
