The Beatles | In My Life (1965)

Its lyrics were written primarily by John Lennon, credited to Lennon–McCartney, who later disagreed over the extent of their contributions to the song. Lennon credited the harmony and bridge to McCartney, while McCartney claimed the entire musical structure. George Martin contributed the piano solo bridge, which was sped up to sound like a harpsichord.

According to Lennon, "In My Life" was his "first real major piece of work" because it was the first time he penned personal lyrics about his own life. The original version of the lyrics was based on a bus route he used to take in Liverpool, naming various sites seen along the way, including Penny Lane and Strawberry Field.

Lennon discarded this lyrical idea in favour of a more generalized meditation on his past. He and McCartney later revisited those original references with their respective songs "Strawberry Fields Forever" and "Penny Lane".

Despite not actually containing a harpsichord, "In My Life" inspired more pop music producers to use the instrument in their arrangements.

In 2000, Mojo named "In My Life" the best song of all time. Rolling Stone ranked it number 23 on its 2004 list of "The 500 Greatest Songs of All Time", and number 98 on the 2021 revised list, as well as fifth on its list of the Beatles' "100 Greatest Songs".
