New York City's Mayor Zohran Mamdani and rapper Cardi B have launched a jingle contest for the city's 2-K program, which aims to encourage families to apply for free child care for two-year-olds. The contest, which includes original 15- or 30-second songs encouraging families to enroll, will be judged by a panel of special guest judges and will air on the radio. The winning entry will be the program’s official theme. All music and lyrics must be original and do not include copyrighted, trademarked, or AI-generated material. Entrants still own their work, but grant the city permanent rights to use, edit, and distribute their jingle in any medium. The program is set to launch this fall with 2,000 free seats and expand to universal access within four years.
