100 Jack FM

100 Jack FM is a radio station format in the United States that operates under the "Jack FM" brand, known for its adult hits playlist and slogan, "Playing What We Want." The format typically features a wide variety of music from the 1970s through the 2000s, often with minimal DJ interaction and a focus on a randomly curated music library. The Jack FM concept originated in Canada and has been adapted by numerous U.S. stations, each tailored to its local market. Stations using the Jack FM brand often utilize a sarcastic and irreverent tone in their on-air imaging. Specific station details vary by location, as "Jack FM" is a format rather than a single station.
