I would think the answer is yes. If a film includes your song, it would
fall under this part of the GPL:

"The 'Program', below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
either verbatim or with modifications..."

This applies even if there's only thirty seconds of your song, or a
modified version of it, in a 90-minute film.

Good point.
