synch license
n.— «Barring an exception under copyright law, the use of a sound recording and/or composition in a film requires a license from the owner (or owners) of the copyrights. Thus, for example, for the film Donnie Darko to feature a slow, stylized version of Tears For Fears’ “Mad World,” a license to the underlying composition—referred to as a “synch license”—would be required.» —“Cinema Law: How Far Can Inspiration Go?” by Greg Korn Kwika Entertainment Law Blog May 5, 2009.
