"What's Going On" is a song by American recording artist Marvin Gaye, released in 1971 on the Motown subsidiary Tamla. Originally inspired by a police brutality incident witnessed by Renaldo "Obie" Benson, the song was composed by Benson, Al Cleveland and Gaye and produced by Gaye himself. The song, which focused on major seventh and minor seventh chords, and was oriented in sounds by jazz, gospel and classical musicorchestration, was mainly viewed as a meditation on the troubles and problems of the world, proving to be a timely and relatable release, and marked Gaye's departure from the Motown Sound towards more personal material. Later topping the Hot Soul Singles chart for five weeks and crossing over to number two on the Billboard Hot 100, it would sell over two million copies, becoming Gaye's second-most successful Motown song to date.
The song topped Detroit's Metro Times list of the 100 Greatest Detroit Songs of All Time, and in 2004, Rolling Stone magazine ranked it the fourth-greatest song of all time; in its updated 2011 list, the song remained at that position. It is included in the Rock & Roll Hall of Fame's 500 Songs that Shaped Rock and Roll list, along with two other songs by the singer. It was also listed at number fourteen on VH-1's 100 Greatest Rock Songs.Source: Wikipedia
