Article talks about Louis becoming a dad and Larry being a fantasy, “though neither has spoken about homosexuality in any real way.” Well... looks like time will tell for both. The parts on Louis’ musical contribution are good:

When Four was released last year, the rock track "Steal My Girl" became the lead single, and "Night Changes" was the sensitive ballad that followed. It was a more mature album as a whole, one which Louis mostly co-penned and which he clearly dominates. It showed the world that he was more than half of Larry, but a real, massively important part of the world's biggest pop group.

Even with the two tracks out there, it quickly became obvious that the best song on the album was "No Control." So obvious, in fact, that fans launched a viral campaign to make it the next single from the record. It didn't happen, but radio stations listened: The song was inescapable.

Not only was it partially a Tomlinson creation, it was a Louis song: He sings the hook, the chorus is his, he makes "No Control." It made everyone pay attention: New Directioners entered the fandom as Louis girls, and old diehards switched their focus to the guy.
