Well, in this new albume, the xx change their style. I was kinda lost in the very beginning, since their first album, Coexist, is totally different: cold, magnetic, somehow depressing and intriguing. I would label the xx in the Coexist era as "quasi-postrock band", but now, as some comments point out in the Youtube comment section, they are grown up, and evolved.
Jesus, I am literally addicted to this song... I would recommend anyone who suffers from depression like me listen to this song. It's full of joy, happiness, and most importantly, hope.
