Please answer the following question: Given the below context:  The film opens in the year 1958, where steel heiress Edna Buxton enters a talent contest. Her overbearing mother is at odds with her, arguing that Edna should choose a specific song and wardrobe for the contest. At the contest, Edna swaps dresses with a blue singer named Doris, and even changes her song at the last minute, infuriating her mother, who leaves before seeing Edna win the competition. An excited Edna decides to use her grand prize winnings to record a demo. The studio producer tactfully delivers the painful truth to Edna that not only are girl singers not getting signed, the record companies are trying to get rid of the ones currently on their rosters. However, when Edna tells him that she wrote the song, he is impressed enough to direct her to Joel Milner who takes her under his wing, renames her "Denise Waverly" and invents a blue-collar persona for her. Milner reworks her song for a male doo-wop group, the Stylettes, as male solo artists are groups are far more marketable. The song becomes a hit. Denise (formerly Edna) moves to New York City and becomes a songwriter in the Brill Building. At a party, she meets the arrogant songwriter Howard Caszatt, and despite an awkward initial meeting they become romantically involved. She also reunites with Doris. Denise offers to and writes a song specifically for Doris and her two girlfriends, persuading Milner to audition and hire the group.  In 1965, Howard and Denise begin writing together; they pen a song called "Unwanted Number," based on a young girl's unwanted pregnancy.  Although it is banned, it attracts the attention of prominent and influential disc jockey John Murray who, despite the negative attention of the song, credits Denise with sparking the craze for girl groups.  Guess a valid title for it!
