What's the most accurate documentary to learn about The Beatles and their music?

Hi all, I am trying to educate myself on the history of music and have found myself watching numerous YouTube videos of The Beatles, Lennon, and McCartney. I am at the point where I would like to watch a documentary that explains their historical, social and cultural importance. Additionally, I don't know where to begin with listening to their songs. Does anyone have a suggested timeline as I am quite confused about this. Thanks in advance.
