Final answer:
Todd would issue a Synchronization License if a filmmaker approached him about using his song in a movie scene where a character sings the song.
Step-by-step explanation:
If a filmmaker approaches Todd Bailey about using a song for a character to sing in a scene of the movie, Todd would issue a Synchronization License. A synchronization license is used when a song is synchronized with visual images, such as in a film or television show. This type of license allows the filmmaker to use Todd's song in their movie, specifically for the scene where a character sings the song.
