"Say Something" is a song recorded by American producer Timbaland, for his third studio album Shock Value II (2009). The song features vocals from Canadian rapper Drake. It was written by Mosley, Jerome Harmon, Graham, Timothy Clayton and John Maultsby. The production was helmed by Mosley under his stage-name Timbaland while Harmon served as the assistant producer, under the stage-name Jroc. The song was tailored to Drake's sound and when the rapper wrote to it, he contacted the producer about the lyrics. Despite the verses feeling more like Graham's record, Mosley gave his blessing and went the product. The song was solicited to digital retailers on November 3, 2009 in the United States as the album's second single.

Timothy Zachery Mosley, known professionally as Timbaland, is an American record producer, rapper, and singer. Born and raised in Norfolk, Virginia, he has received widespread acclaim for his innovative production work and distinctive "stuttering" rhythmic style. In 2007, Entertainment Weekly stated that "just about every current pop trend can be traced back to him—from sultry, urban-edged R&B songstresses [...] to the art of incorporating avant-garde sounds into No. 1 hits."
