Philosophy of the World ( en.wikipedia.org )
The Shaggs had no interest in becoming musicians and never became proficient in songwriting or performing. Philosophy of the World features bizarre songs with badly tuned guitars, erratically shifting time signatures, disconnected drum parts, wandering melodies and rudimentary lyrics about pets and families. It has been described as both among the worst records of all time and a work of "accidental genius".
