It's All Too Much by The Beatles is a psychedelic rock song from the United Kingdom that explores themes of overwhelming love, cosmic consciousness, and the interconnectedness of life. The lyrics express a sense of being awash in sensory experiences and emotions, reflecting the band's experimentation with mind-expanding substances during the 1960s. Key themes include the euphoria of love and the mystical unity of all things. The repetition of the line 'It's all too much' underscores the sensation of being overtaken by the magnitude of these experiences, adding to the song's psychedelic and spiritual ambiance.
