Since I've Been Loving You

Led Zeppelin's "Since I've Been Loving You" is a powerful blues-rock ballad that delves into the emotional turmoil of unrequited love and the toll it takes on the narrator. The song, featuring the band's signature blend of bluesy guitar riffs and soulful vocals, captures the essence of the blues genre while showcasing the band's musical prowess.

The lyrics speak of a person who is working tirelessly, from seven to eleven every night, which becomes a metaphor for the effort and energy put into a love that is not reciprocated. The repetition of 'I've really been the best, the best of fools' suggests a self-awareness of the futility of their actions, yet they continue to love passionately. The phrase 'I'm about to lose my worried mind' conveys the mental and emotional strain that the situation is causing, indicating a near breaking point.

The song also touches on themes of betrayal and heartache, as evidenced by the lines 'I open my front door, hear my back door slam' and 'You had the nerve to tell me you didn't want me no more.' These lyrics paint a picture of a lover who has been left for someone else, the 'newfangled back-door man,' which is a blues expression for a secret lover. The raw emotion in the song is further amplified by the powerful vocal delivery and the expressive guitar solos, which are characteristic of Led Zeppelin's style and the blues genre as a whole.
