Final answer:
In the case of a songwriter writing a song for a movie, they do not always give up their publishing rights but retain royalties as a songwriter.
Step-by-step explanation:
In the case of a songwriter who writes a song for a movie, it is false that they always give up their publishing rights in the song but retain their right to royalties as a songwriter.
Typically, when a songwriter creates a song for a movie, they will negotiate a contract that specifies the rights and royalties associated with the song. While it is possible for a songwriter to give up their publishing rights, it is not a requirement. They may choose to retain their publishing rights and receive royalties as a songwriter.
For example, a songwriter could negotiate a deal where they retain their publishing rights but also receive royalties for the performance of the song in the movie, as well as any subsequent use of the song.
