"Four" follows the release of the group's first three chart topping album, "Midnight Memories," "Up All Night" and "Take Me Home," which landed them a Guinness World Records honor of being the first group to debut at No. 1 with their first three albums.

Very few details about the album have been revealed but the group gave fans an early taste of the effort on Monday by releasing a free download of the track "Fireproof" on their website.
