The song has "martial arts", "pounding piano keys" (played by Neil Crowley) and "chanting backing singers". Critics have said Adele's vocals are like <nowiki>Wanda</nowiki> Jackson's "dirty-blues growl." AOL Radio Blog's Nadine Cheung says the song is "sung from the perspective of a scorned lover, who is finally able to see the light, but despite regretful sentiments, reconciliation is not an option here."
