"Shape of My Heart" is a song by American boy band Backstreet Boys, released on October 2, 2000, as the lead single from their fourth studio album, Black & Blue (2000).^[2] The ballad was written and produced by Max Martin and Rami and co-written by Lisa Miskovsky. Following its release, "Shape of My Heart" topped the singles charts of eight countries and reached the top 10 on 15 others, including the US Billboard Hot 100, on which it peaked at number nine. The song earned a Grammy Award nomination during the 44th Grammy Awards for Best Pop Performance by a Duo or Group with Vocals.

Due to the success of rival boy band NSYNC's album No Strings Attached selling over 2.4 million copies in its first week, there were high expectations from industry experts and fans that the Backstreet Boys' next album Black & Blue would break the first week sales of No Strings Attached.^[3] "Shape of My Heart" was widely anticipated as the lead single of Black & Blue, which would follow their previous singles "Quit Playing Games (With My Heart)", "Everybody (Backstreet's Back)", and "I Want It That Way".^[3]

"Shape of My Heart" is stated to be "the sound of a boy band becoming a group of men".^[3] It consists of a bubblegum chorus, clean pop structure, along with various vocal harmonies from Max Martin's production. It also contains soft-pop guitar, low-key percussion, and a lyrical emphasis on the reflection of past mistakes.^[3]

The song is performed in D major^[4] with a key change to E major at the third chorus.^{[citation needed]}

Craig Seymour of Entertainment Weekly gave the song a C− in his review, stating that the "mid-tempo ballad is more a joyless retread than a maturing makeover". Jason Lipshutz of Billboard considered the song to be a disappointment, stating that it was a muted mid-tempo reflection on mistakes and weaknesses, as well as being "miscast as a flashy comeback that would return serve against *NSYNC and hijack pop radio for months".^[3]

The song reached number 9 on the Billboard Hot 100 in the United States, giving the group their sixth and last top-10 single in the US, while reaching number 8 on the Billboard Mainstream Top 40 chart.^[5] It also topped the charts in Canada, Italy, the Netherlands, New Zealand, Norway, and Switzerland as well as the top 10 in several other countries.

The song was the last single by the Backstreet Boys to peak in the top-ten of the Billboard Hot 100 chart.^[3] Jason Lipshutz stated that the song's influence spread to future Backstreet Boys singles such as "Incomplete", "Show 'Em (What You're Made Of)", and "Don't Go Breaking My Heart", concluding that although it wasn't a smash, it has become "an important inflection point for one of the era’s biggest groups".^[3]

In 2008, one of the song's writers, Lisa Miskovsky, released her own version of the song, "Another Shape of My Heart" on her 2008 album Last Year's Songs: Greatest Hits.^{[citation needed]}
