Vinyl LP pressing. Songs You Know by Heart: Jimmy Buffett's Greatest Hit(s) is the 18th album and the first greatest hits compilation by singer/songwriter Jimmy Buffett. It was released in January 1, 1985. The parenthetical "s" in the subtitle alludes to the status at the time of "Margaritaville" as Buffett's single large chart hit. Although the album charted at 100 on the Billboard 200, it is currently certified 7x Platinum by the RIAA, making it Buffett's most commercially successful. Despite it's 1985 release date, the album only includes songs from 1973 to 1979. Aside of 1976's Havaña Daydreamin', this compilation includes at least one song from every album released between 1973 and 1979.
