‘A Hard Day’s Night,’ the third album by The Beatles, came just fifteen months after their debut record. In that short space of time, Lennon/McCartney’s songwriting has developed so exponentially, that they were able to release an album solely consisting of original material and is The Beatles only album written 100% by Lennon/McCartney. They had shift from a Rock ‘n Roll sound to a more Pop sound, still with a Rock ‘n Roll edge, of course.

The Beatles’ fifth album doubled as the soundtrack to the film of the same name and marked the end of their “early” period or first half of their career. The albums following this one were more complex and experimental, both in production and songwriting. It was also the last time an album by The Beatles would feature any songs not written by any of the members (bar traditional song, ‘Maggie Mae’ on ‘Let It Be’).
