Since 1975 Chusid has been a DJ on free-form radio station WFMU, where he hosted an unpredictable and idiosyncratic weekly program whose content he calls "genre-surfing tokenism". In June 2020, he left the weekly schedule, but remains on the air staff. Prior to his involvement at WFMU, he worked briefly at WPKN radio from 1969-1971 while an undergrad at the University of Bridgeport (which he left after two years); in 1977, while living in New Orleans, he hosted a weekly program on WTUL. In 1988, he served as a comedy writer for author/humorist Tom Bodett's syndicated radio series, "The End of the Road".
