Songwriting credits on FOUR, based on BMI, ASCAP, and APRA AMCOS listings. Songs in blue don’t have any members of 1D credited. Songs in red have incomplete listings or no listing at all - as far as I know there’s nothing anywhere about Act My Age, and APRA AMCOS has a character limit on the composer field that has left some of its listings incomplete - it only lists Liam, Louis, and Niall on Change Your Ticket, where BMI lists the entire band, so it’s possible/likely that the same thing happened to the listings for Fool’s Gold and Night Changes.
