"Anyone Who Knows What Love Is (Will Understand)" is a 1964 R&B song written by Jeannie Seely, Randy Newman, Judith Arbuckle and Pat Sheeran.

First sung by a character for a talent show in "Fifteen Million Merits" (2011), it was used in five subsequent episodes, and began to appear in other films and television programs.

Seely was a 23-year-old secretary at Liberty Records and conceived of the song while reading a pantyhose advert that said, "Anyone who knows what comfort is..." She stayed after work to use the label's piano, but struggled to play the chords and first verse as it sounded in her head.

[7][11][12] The recording process under Imperial was more involved than that of Thomas's previous discography, with use of orchestras, vocal ensembles, timpani and overdubbing.

[7] "Time Is on My Side" was originally an orchestral jazz instrumental composed by Jerry Ragavoy and recorded by trombonist Kai Winding in 1963.

[16][12] The Rolling Stones covered this version the same year, and it became their first top ten single in the U.S.[14][15] "Anyone Who Knows What Love Is (Will Understand)" is a rhythm and blues song with elements of Motown.

[18][19] Newman biographer Kevin Courrier described the song as fitting the trope of "the sacrificial woman who stands by her no-good man", which is a longstanding theme in blues music.

He contrasts this with the later song "While the City Sleeps", written by Newman and performed by Thomas, which "turns the tables" in describing a woman cheating on her male partner.

[5] Creator Charlie Brooker chose it for "Fifteen Million Merits" (2011), as a symbol of a past era to juxtapose with the dystopian setting.

[27] A reviewer, Paste's Katherine Connell, wrote that the song's "authenticity" against the "artificiality" of the setting is what attracts Bing to Abi.

[30] The song was reused by the production throughout the series, as a way of "nesting all the episodes together in an artistic universe of sorts", according to executive producer Annabel Jones.

[31][32][33] Price argued in Black Mirror and Philosophy that in each case, the song is thematically relevant as it is sung either by or to characters who "don't know what love is".

[41] Seal said that the song sounded like the music his mother listened to in his childhood in the 1960s, and could have been sung by Dionne Warwick or Tammy Wynette, or produced by Phil Spector.

[42] Jay Cridlin of the Tampa Bay Times praised a live performance of the song with orchestral backing as a "stirring, starlit romance" with "wall-of-sound percussion".
