"Weight of the World" was released as a promotional single in October 2007 exclusively in Colombia. "Together Again", a track recorded for "The Open Door" which was later rejected, was made available as a free digital download on January 22, 2010, to benefit the United Nations Foundation for their recovery efforts following the Haiti earthquake. Lee spoke of the recording, "I am deeply moved by the tragic loss and devastation in Haiti. We hope to be able to make a positive contribution to the UN's emergency response by teaming with the UN Foundation through our music." The song was released as a digital download by online retailers on February 23, 2010; it peaked at number 86 on the Canadian Hot 100. In a 2004 interview with MTV News, Lee said she was composing music for the film "", where its producers had offered her a small role; regarding this, the singer said, "They were like, 'Do you want to do a cameo?' And I was like, 'Hell yeah! Let me die. I want to be somebody who gets murdered.' So I don't think that's going to happen." It was later also revealed that the album track "Lacrymosa" was originally written for the film but was not included in it. According to the film's producers, neither Lee nor the band were approached to compose music for the film. Reportedly, another track was completed for the movie, but was rejected due to its dark sound.
