Feel Good Inc.

The song's harmonic identity is defined by the contrast between the gritty, rhythmic tonic-drone of the hip-hop verses and the lush, multi-layered Aeolian harmony of the chorus. By using minor 7th extensions (i7, v7, iv7), the track leans into a jazz-inflected 'cool' sound, while the bassline utilizes blues-scale mechanics to provide the groove. The lack of a major V (dominant) chord is crucial; it prevents the song from feeling 'resolved' or 'classical,' keeping it firmly in the alternative/electronic aesthetic.

The song began as a demo recorded by Damon Albarn. Seeking a fresh direction for the second Gorillaz album, Albarn collaborated with producer Danger Mouse. The track was built around a prominent bassline and a contrast between Albarn's melodic, melancholic '2D' vocals and the energetic rap verses from De La Soul. The rap group was brought in specifically to provide a high-energy counterpoint to the song's darker undertones.

As the lead single from 'Demon Days,' this track solidified Gorillaz's status as a global phenomenon by bridging the gap between underground hip-hop and mainstream rock. It combines De La Soul’s energetic delivery with a hauntingly melodic chorus to explore themes of isolation and mass-media escapism.
