# Mercy (Duffy song)

"Mercy" is a song performed by the British soul singer Duffy, released as the second single from her debut studio album, Rockferry (2008). Co-written by Duffy and Steve Booker and produced by Booker, it was released worldwide in 2008 to critical acclaim and unprecedented chart success. As Duffy's first international release, the song is credited with firmly establishing her career and is now considered her signature song. "Mercy" received comparisons to Duffy's previous single, "Rockferry". Critical reviewers of "Mercy" noted similarities between the song to releases by Aretha Franklin, Dusty Springfield and the Supremes, as well as contemporaries such as fellow British singer Amy Winehouse.
"Mercy" was nominated for several awards in 2008, including the Grammy Award for Best Female Pop Vocal Performance at the 51st Grammy Awards. Well received by the public, "Mercy" peaked at number one on the UK Singles Chart in February 2008, remaining atop the chart for five weeks, and went on to become the third-best-selling single of 2008 in the United Kingdom, with sales of over 500,000 copies in the UK that year. It achieved worldwide chart success, topping the charts in Austria, Germany, Greece, the Netherlands, Norway, Republic of Ireland, Switzerland and Turkey, and peaked within the top five of the charts in Belgium, Denmark, France, Italy, Japan, New Zealand, Romania, Spain and Sweden. Duffy attributed the chart success to the fact that "everyone is searching for liberty ... from themselves or from the world they’ve created around them" and "everyone would like to be set free". It is Duffy's best-selling single to date.
The song has been covered several times since its original release, most notably by the cast of American musical television series Glee as well as by both The Fratellis and OneRepublic on BBC Radio 1's Live Lounge. The Glee version charted on the UK Singles Chart and in Ireland, and Duffy herself performed the song for the Live Lounge. The song was performed live at various music festivals as well as on Duffy's 2008–09 tour. Lynda Carter released her version of the song on her 2018 album "Red Rock & Blues."

## Writing and inspiration

"Mercy" was written by Duffy and Steve Booker during the final stages of completion for Rockferry. In an interview with Mojo, Duffy noted that she "felt something was missing and 'Mercy' was that missing thing", saying that herself and Booker were "writing it literally at the end, when the strings were being put on 'Rockferry' and 'Warwick Avenue". Duffy first met Booker by chance because she bought the flat in Ladbroke Grove that Booker had been renting. Booker's girlfriend met Duffy and then introduced the pair. Duffy has later noted of the experience:
   "We went for coffee and I had this gut feeling that we should write together. I asked Jeanette [Lee] what she thought and she just said, we’ve made this record so go and have fun, be creative. By the end of hanging out in the studio for two weeks we had 'Mercy' and 'Stepping Stone'."
Duffy had already written the lyrics to "Mercy" before her meeting with Steve Booker, although she has since said that she "never [has] a plan as that always fails", in reference to the writing of the song. Duffy has noted that during recording with Booker, "Mercy" "was like this melodic poem in my mind, which I just had to get out, and I knew exactly what I wanted it to sound like". She has also said that they "built the song from the bottom up", also noting that it is "very important that my songs start from an organic source, rather than a drum loop". When asked of the lyrical meaning of the song, Duffy said:
   "The lyrics were about having a feeling towards someone, whether it’s a romantic feeling or just some chemistry that you don’t want, and you desperately want to be released from that feeling."
According to Duffy, "Mercy" is autobiographical and is about "sexual liberty" and "not doing something somebody else wants you to do". Duffy has also said in an interview with Observer Music Monthly that she sings "Mercy" "several times a day and it's just like having sex every time". However, Duffy has expressed fear "about saying what a song is about" because she felt that the lyrical interpretation is her "issues and baggage and when someone else listens to the song it isn’t about my baggage anymore it’s about their baggage". According to Mark Edward Nero of About.com, the song is "a tale of lust".
In an interview with HitQuarters Booker said he searching for a song that you could imagine sending the audience crazy on the 1960s UK pop show Ready Steady Go!. After first trying to match "Stepping Stone" with this idea he then sang the fledgling "Mercy" and found it fit.

## Music structure and composition

"Mercy" is set in common time, with a tempo of 130 beats per minute and is written in the key of G major. Duffy's vocal range spans from D$_4$ to D$_6$.
Lyrically, "Mercy" is about "intense longing for an attractive guy". Mark Edward Nero of About.com noted that "[although] the song sets the stage for who Duffy is as an artist as well as a person" it was "still fairly tame, lyrically". The BBC Chart Blog compared the song to Aretha Franklin's "Chain of Fools" and "Where Are You Baby?" by Betty Boo.
The introduction to "Mercy" is similar to the opening bars of "Stand by Me" by Ben E. King. The sound is slightly different from that of "Stand by Me", however, because "Mercy" uses the 1st, 5th and flattened 7th degrees of the scale, instead of the 1st, 5th and major 7th. This change creates a bluesy sound. The song is written in the 12-bar blues form, using the chords I7, IV7 and V7.

## Critical reception

"Mercy" garnered overwhelming acclaim from critics, often being praised for its catchy bass line and "summery", jazzy themes. Digital Spy gave the single a positive review, noting that the single was "a catchy, danceable Northern soul pastiche" and that the "baseline practically reeks of sweat and stale cigarette smoke". The Times in a review for Rockferry said that "Mercy" is "a slight but darned catchy number" and "a classic radio hit". The reviewer also drew comparisons between "Mercy" and Amy Winehouse's critically acclaimed single "Rehab". The Independent said that "Mercy" and "Rockferry" "are tracks that stand out as something special", whilst noting that the "uptempo organ funk" provides "the album's one truly memorable groove". PopMatters said that the song was "still grounded in a bouncing Motown rhythm but [with] the added colour of jaunty keyboards", whilst again comparing the song to "Rehab".
The Observer, in an extremely positive review for Rockferry, said that "Mercy" "is a big, booming, finger-wagging sashay worthy of the Supremes". In a positive review for Rockferry, American music magazine Billboard said that "Mercy" "is about as summery as summery gets". NME, giving Rockferry a negative review, had a mixed attitude towards "Mercy", comparing the song's "Austin Powers organ" to work by Aretha Franklin. Slant said that the song has a "bass-heavy syncopated beat, "Yeah, yeah, yeah" refrain [and an] obvious '60s-pop frame of reference". However, the song was given negative comparisons to Amy Winehouse. "Mercy" also appeared on various critics' "Top" lists. Bill Lamb of About.com placed "Mercy" at number 29 in a list of his favourite 100 songs of 2008. Fred Bronson of Billboard placed "Mercy" at number two, whilst the magazine's Keith Caulfield placed "Mercy" in an alphabetical list of his favourite songs of 2008.
   "60's pop star Dusty Springfield is smiling from beyond every time Duffy opens her mouth to sing."

### Awards and other recognition

"Mercy" won the 2008 MOJO Award for Song of the Year. MOJO editor Phil Alexander called the song a "timeless" classic that "could really have come from any period in time over the last 50 years". The single was nominated for a BRIT Award in 2009, for Best British Single. Duffy's performance of "Warwick Avenue" at the ceremony helped to increase sales of "Mercy" by double the market average before the broadcast. The song was also nominated for a Grammy Award in the category "Best Female Pop Vocal Performance". The song was also nominated during various award ceremonies including the MTV Europe Music Awards (Most Addictive Track), Q Awards (Best Track) and the 2009 Music Producers Guild Awards (UK Single of the Year). "Mercy" was also nominated for PRS for Most Performed Work and Best-selling British Song at the 2008 Ivor Novello Awards, winning in the former category. The song was the fourth most played anywhere in the United Kingdom in 2009, revealed in a list compiled by music body PRS.

   "I think I’m a bit all-over the place, I can't quite handle it. I was aiming for top 40, possibly top 10, so I can genuinely tell you I am really blown away."
"Mercy" entered the Australian ARIA Singles Chart at number 50 on the issue date of 4 May 2008, reaching a peak of 26 nearly five months later, on 14 September 2008, after staying on the chart for eighteen weeks.

"Mercy" debuted on New Zealand's RIANZ singles chart at 40, eventually peaking at number four.

"Mercy" also topped the Hungarian Airplay Chart, Dutch Top 40, German Singles Chart, Greek IFPI Singles Chart, Norwegian Singles Charts, Swiss Singles Chart and the Ö3 Austria Top 40, amongst others.

## Music videos

The main-release music video for "Mercy", directed by Daniel Wolfe, features Duffy standing on top of a platform performing the song. Featured in the video are Northern soul dancers who dance to "Mercy". Choreographed by Natricia Bernard, the dancing involves elaborate moves, including the use of fire. "Mercy" was nominated for two awards at the UK Music Video Awards, for "People’s Choice Award" and "Best Pop Video". The music video was released to the UK iTunes Store on 26 January 2008, being the first release of "Mercy". In reaction to the video, RealMusic noted that Duffy "does manage to stand atop those platforms very well and sing without falling off in [the] video, so top marks for that".
A second music video release was made for the United States market, directed by Adria Petty. It shows Duffy performing live on stage whilst people dance to the song. The US version was given a positive review by Nick Levine of Digital Spy, who wrote that "It's glossy, full of young, good-looking types and proudly features a drum with Duffy's name printed on its skin – hey, that's success for you."

## Cover versions and usage in media

"Mercy" has been covered several times since its release. In 2008, American band OneRepublic recorded a version of the song which was first heard as a live cover on the BBC Radio 1 Live Lounge. Their version of the song later appeared, in live format, on the band's third single "Say (All I Need)". OneRepublic then recorded a studio version of "Mercy" as a bonus track for their second album Waking Up (note that the track is not to be confused with another OneRepublic song and single, also titled "Mercy" and released on their debut studio album, Dreaming Out Loud).
The Fratellis also recorded "Mercy", mixed with the Minder theme tune, specially for broadcast on the Live Lounge. Duffy herself also recorded "Mercy" live for the Live Lounge. In the broadcast, Duffy also sang a cover of Hot Chip's single "Ready for the Floor". British production team The Third Degree recorded a version, released 9 March 2009 on the Acid Jazz label as a 7-inch vinyl record. Singer John Mayer also covers the song as a slow blues in many of his live shows.
The cast of the US "musical comedy" television series Glee covered the song for the third episode of the first series, "Acafellas". The cover was called "leg-splits-over-shoulders exciting" by The Wall Street Journal. The Glee cast's cover version was released as a single worldwide to promote the series, and reached numbers 94 and 49 on the UK and Irish singles charts, respectively.
This song also appeared on the soundtrack of the video game FIFA 09.
