6. In My Life — The Beatles (1965)
This tremendous track was quite meaningful to Lennon. When it came out, The Beatles transitioned slightly from cheery generic pop to a bit more of a personal feel. In particular, this song spoke about Lennon’s existence in Liverpool — and his life before becoming a member of the band. The use of a harpsichord within the musical arrangement spurned a trail-blazing trend for other composers in popular music.
