A.M.

This end-of-night tribute to good times is the closing track of the deluxe edition of Made In The A.M. It's the only song on the album that Harry Styles, Liam Payne, Louis Tomlinson and Niall Horan all co-wrote. The four 1D band members penned the cut with regular collaborators Julian Bunetta, Jamie Scott, John Ryan and Ed Drewett.

The reasoning behind the album title is that much of it was written and recorded during the early morning hours. "A lot of the time we did it after shows, writing sessions after the shows and it kind of just seems to be the way we've done it now for the last two or three albums," Louis told Clyde 1 Radio.
