Shinzō wo Sasageyo!

"Shinzō wo Sasageyo!" (Japanese: 心臓を捧げよ！; lit. 'Dedicate your Heart!') is the eleventh track created by the Japanese band Linked Horizon for their second album Shingeki no Kiseki. Originally released in a shortened version on 2 April 2017 to be used as the third opening for the anime Attack on Titan, the full version would be released as part of the album about one month later on 17 May 2017. The song was composed by the band's head musician Revo, who constructed the song after re-reading the anime's manga multiple times, drawing phrases directly from it in some instances, including the song's title.

While the song would not be as successful as their first anime opening "Guren no Yumiya", it would still be played at a number of concerts, and would be nominated for two awards in 2017. The song would also receive Gold certification from the Recording Industry Association of Japan in October 2018, and become Linked Horizon's first song to reach 100 million streams on the audio streaming service Spotify in December 2021.
