"I Feel Fine" is a song by The Beatles. It is notable for its beginning-guitar-player-challenging guitar riff, which, although complex, is nowhere near as complex as the riff for "And Your Bird Can Sing". "I Feel Fine" is said to be proto-Psychedelic Rock, like how "Helter Skelter" is said to be proto-Heavy Metal; in actuality, "I Feel Fine" is proto-proto-Psychedelic Rock, and "Helter Skelter" is the very first Heavy Metal song.
