He contributed songs to Broadway revues, formed the music publishing company Spier and Coslow with Larry Spier and made a number of recordings as a performer.
With the explosion of film musicals in the late 1920s, Hollywood attracted a number of ambitious young songwriters, and Coslow joined them in 1929. Coslow and his partner Larry Spier sold their publishing business to Paramount Pictures and Coslow became a Paramount songwriter. One of his first assignments for the studio was the score for the 1930 film The Virtuous Sin. He formed a successful partnership with composer Arthur Johnston and together they provided the scores for a number of films including Bing Crosby vehicles.

During the 1960s Coslow's work shifted from music and film to market analysis.
