Somebody That I Used to Know [SEP] Critical reception
Allmusic's Jon O'Brien felt the track was an "unexpected chart-topper ... [it] is an oddball break-up song whose stuttering rhythms, reggae hooks, and hushed vocals sound like The Police as remixed by The xx". Writing for Digital Spy, Lewis Corner rated the song four stars out of five and described it as "a Bon Iver-styled ballad for the music-buying masses". Martin Davies from Click Music gave the song five stars out of five and stated that the song is "that rare example of a track that hits you squarely between the eyes". In November 2011, music blog This Must Be Pop predicted the song as a post-Christmas UK hit.
