“Feel Good Inc.” is about criticism of herd mentality, isolation, and escapism.

The music video features computer-generated imagery combined with 2D animation. The inspiration for the video came from Hayao Miyazaki’s 1986 animated film Castle in the Sky.

The lead single from Demon Days peaked at No. 2 in the United Kingdom and No. 14 in the United States, being the only song in Damon Albarn’s career to reach the Billboard Top 40. Not only that, but it won the band a Grammy for Best Pop Collaboration with Vocals, also being nominated for Best Record of the Year and Best Music Video.
