Eventually we'll have to discuss, if there will be someone, or more then someone who'll be in the post production part, if they'll add music, likely difficult unless they do their own music for the thing. I don't the legal thing concerning this, or maybe no music, sound effects. There may be some generic sound effects and maybe some free sound effects that anyone is allowed to download and use, maybe even for something the sound effect was not intentionally designed and labeled for, or making up some of their own sound effects from ordinary items.
