"Diamonds from Sierra Leone" (originally "Diamonds") was produced by West, Jon Brion, and Devo Springsteen. The producers, with the exception of Brion, are credited as songwriters alongside John Barry and Don Black, who both received credit due to their composition being sampled. The song was initially centered around the demise of Roc-A-Fella Records, though was later re-recorded once West learned about blood diamonds in Sierra Leone. West premiered the song for Hot 97 on April 20, 2005, before it was sent to US mainstream radio stations the following month as the album's lead single, through Roc-A-Fella and Def Jam. In the chorus, West interpolated the phrase "forever ever, forever ever" from OutKast's "Ms. Jackson". A hip hop song, "Diamonds from Sierra Leone" features a sample of "Diamonds Are Forever", performed by Shirley Bassey. Lyrically, it sees West connect his material wealth to Sierra Leone's blood diamonds and the resulting civil war. The song received generally positive reviews from music critics, who mostly complimented West's lyricism. They often emphasized the rapper's focus on his status, while some critics praised the sampling of "Diamonds Are Forever". The song was awarded Best Rap Song at the 48th Annual Grammy Awards and won one of the Pop Awards at the 2006 BMI London Awards, before being named by Slant Magazine as among the best singles of the 2000s decade. - Wikipedia
