Don Williams was an American country singer-songwriter known for his smooth, baritone voice and straightforward yet poetic lyrics. His musical style, often described as "gentle country," was marked by a relaxed tempo and a focus on melody and lyrics, which set him apart in the country music scene of the 1970s and 1980s. Williams was particularly influential for his contribution to the "countrypolitan" sound, a subgenre of country music that incorporated pop elements. Among his most notable works are hits like "I Believe in You," "Tulsa Time," and "It Must Be Love."
