So Fresh is an Australian compilation album series. It began in 2000, as a joint venture from Sony, BMG (later merged into Sony) and Universal, replacing the prior Hit Machine series, which ran from 1993 to 2000. Since 2000, So Fresh albums have been released four times per year, named after each season (Summer, Autumn, Winter and Spring), consisting of current hit songs from artists signed to Sony, BMG or Universal.
