"Lost in You" is a song by British singer-songwriter Rod Stewart, released in 1995 as a single from his eighteenth studio album, A Spanner in the Works. The song was written by Rod Stewart, Ronald Isley, and Angela Winbush, incorporating elements or interpolating the 1987 song "Lost in Your Love" by the Isley Brothers.
Musically, "Lost in You" is a heartfelt ballad that blends elements of pop and soft rock. It showcases Stewart's signature gravelly vocals delivering a romantic and devoted lyrical theme. The production is characteristic of 1990s adult contemporary music, featuring lush instrumentation.
Upon its release, "Lost in You" performed moderately well on international charts. It was a Top 20 hit in the United Kingdom, peaking at number 12 on the UK Singles Chart. In the United States, it achieved success on the Adult Contemporary chart, reaching number 5, reflecting its appeal to a more mature audience. While it did not reach the Billboard Hot 100, its strong performance on the Adult Contemporary format solidified its presence on radio. The song remains one of the notable tracks from the A Spanner in the Works album, which marked a return to a more rock-oriented sound for Stewart after several years focused on standards and acoustic material.
