JD Souther, a monumental figure in the Southern California country-rock movement of the 1970s and a key songwriter for the Eagles, passed away on Tuesday at the age of 78 at his home in Sandia Park, New Mexico. His passing has left a profound void in the world of music, with tributes pouring in from fans and fellow musicians alike.

The announcement of his death was publicly shared on his official website, though no specific cause was revealed. Souther was renowned for penning timeless hits not only for the Eagles but also for Linda Ronstadt and James Taylor, leaving an indelible mark on the music industry.

Emerging as a prominent figure in the late 1960s, Souther was heavily involved in the vibrant Los Angeles music scene. He frequented celebrated venues like the Troubadour in West Hollywood and was a part of a close-knit group of artists who shaped the era's sound. Souther's writing prowess produced classics such as "Faithless Love," "White Rhythm and Blues," and "Her Town Too," showcasing his ability to blend rock and country influences seamlessly. Notably, he co-wrote the Eagles’ last No. 1 single "Heartache Tonight," solidifying his status as a hitmaker during a golden age of music.

After reaching remarkable heights in his career, Souther took a step back from the music scene as tastes began to shift away from his style. He candidly expressed his desire for a quieter life in a 2012 interview with Rolling Stone, stating, “All the men in my family worked until they died, and I’m going to take a few years off and build a great house and have a life.”

While he stepped back from music, Souther ventured into acting, making appearances in various film and television productions. He notably played a piano player in Steven Spielberg's "Always" and later joined the cast of the acclaimed TV series "Nashville" as Watty White, a seasoned music producer, drawing on his own experiences in the industry. His role became beloved, leading to his return in the show's fifth season.

Born John David Souther on November 2, 1945, in Detroit, Michigan, Souther's musical journey began at a young age. His father was a big band singer who traveled extensively, which eventually led to the family moving to Texas. There, Souther developed his musical talents, initially engaging with various instruments and eventually honing his songwriting skills in the studio his family owned.

Throughout his life, Souther formed deep connections with several influential artists, famously dating Linda Ronstadt, Stevie Nicks, and Judee Sill, whose music sometimes reflected their romantic entanglements. He was twice married, with both marriages ultimately ending in divorce, and was survived by his two sisters, Susan Burt and Shari Smeaton.

In recent years, Souther returned to recording with a jazz-influenced style and released multiple albums, the latest being "Tenderness" in 2015. He had upcoming performances scheduled, indicating his enduring dedication to music up until the end of his life.

Reflecting on his legacy, JD Souther expressed contentment with the fame of his songs rather than his own celebrity. "I like that I don't have to check my hair before going out," he shared with Variety, encapsulating his humble disposition. As the music world mourns the loss of this extraordinary artist, fans remember him not only for his remarkable contributions but also for the legacy of influential music that will continue to inspire future generations.
