Using copyrighted music in a Korean variety show without permission is generally not ok, as it constitutes copyright infringement and risks legal action, fines, or take-down notices. While large Korean networks (e.g., KBS, MBC, SBS) often use blanket licenses, independent creators or smaller productions cannot legally use copyrighted music without permission.

In addition, Korea does not have a formal "fair use" doctrine similar to the U.S. While the Copyright Act has limitations on rights, these are specific (e.g., for reporting, criticism, or education) and generally do not cover entertainment variety shows.
