Country USA was a 23-volume series issued by Time-Life Music during the late 1980s and early 1990s, spotlighting country music of the 1950s through early 1970s. Each volume in the series chronicled a specific year in country music, from 1950 through 1972, and was issued on a double-length compact disc or cassette, or two vinyl albums. Individual volumes contained 24 tracks, usually representing the year's most popular and important songs. Also included was a booklet, containing liner notes written by some of the most respected historians of the genre, photographs of the artists, and information on the songs (writers, performers and peak position on Billboard magazine's country charts).
