"Sweet Disposition" is a song by Australianindie rock band The Temper Trap. Described by critics as an "indie anthem", the song was written by Dougy Mandagi and Lorenzo Silitto. It was not a huge success initially in Australia, and fared better in Japan and Europe. Renewed interest in the song was generated after it was included in the soundtrack for the 2009 film 500 Days of Summer–eventually reaching number nine on the Billboard Alternative Songs chart in the United States.
Despite The Temper Trap originating from Australia, "Sweet Disposition", the lead single from the debut album Conditions has proved to be more popular in the UK and Ireland, reaching No. 6 (in the week beginning 11 October 2009) and No. 8 respectively, while it only reached a peak of No. 14 in Australia.
In the Japanese charts, it reached No. 15. The song reached No. 9 on Billboard's Alternative Songs chart, due to interest in the song after it appeared in the film (500) Days of Summer. In 2014, it was featured in the action film 3 Days To Kill starring Kevin Costner.
There are three music videos for the song. The Australian/domestic version, directed by Madeline Griffith, features the band performing alongside slow motion footage of light bulbs smashing on the floor.
The UK/international version directed by Barnaby Roper, features a girl roller blading through space, past transparent images of each band member. That version was also played in Australia following the song's increase in popularity in 2010. The US version, directed by Daniel Eskils, was released in March 2010. This version displays the band members playing around with musical instruments as well as demolishing them, this all being taped with a high-speed camera. Also, instead of the key signature being in D major like the recorded song, the music video version is in C-sharp major.
