Four is undeniably One Direction's best album ever. It is clear, especially through this album, that the members have drastically grown up and matured so fast in a matter of a few short years. I think the boys have started to become more involved in their song-making process with this album, and it really shows through; the lyrics in the more slower and 'serious' songs are very deep and touching. This album would be one of the few that I could listen to on repeat for the rest of my life.
