"She's a Woman" emerged from Paul McCartney's desire to craft a bluesy song in the style of Little Richard, with much of it written swiftly, even on the day of its recording. The lyrics express a deep connection, notably containing the first reference to drugs in a Beatles song with the line "turn(s) me on." Musically, it features a sparse arrangement that allows the bass to take center stage, anticipating McCartney's prominent bass lines in later works. Playing this song channels a raw, energetic devotion, celebrating a powerful attraction.
