Hook (music) - Use in Market Research

Use in Market Research

The hooks of songs may be used in market research to assist in gauging the popularity of a song by the recognizability of its hook. Often radio stations conduct "call out" either on the Internet, via telephone, or a music test (either online or in an in-person setting) to conduct surveys. Stations may use the services of a professional "hook service" or prepare the materials themselves. Hooks used are typically seven to ten seconds long.
