About the making of's music (of my short film)

Hi again! It's Jesús Barrio Caamaño.

I'm preparing my short film's making of, and I'm using a song for that (like if the making of was a kind of music video).

My question is:

-Is it appropiated that the song appears in the soundtrack part, like this:

"Plata" (music for the making of)

Written and performed by Andrea Garcy

-Or it's better that this appears in the TRIVIA zone, like this:

-The short film has a making of, with the Andrea Garcy's song "Plata" as a soundtrack.

Please, tell me about this.

Thanks!
