1. Original Music
That is music you created yourself or hired a composer to score for you. That is great. If you had someone make the music for you, just make sure you have an email or simple release stating it’s okay to use.
2. Licensed Music
That’s another great option. Licensed music is music you don’t own and isn’t exclusively for your film, but you get permission to use, either for free or for a small fee. Maybe you have a killer song a friend made. Or maybe you want to license something from another artist. Read below for our list of music licensing resources.
3. Non-Licensed Music from another Film or a Big Artist
This is not cool. First of all, it’s illegal and you could get in serious trouble. Second of all, it goes against everything a fellow artist should stand for. Please don’t use music in your film you don’t have permission for.
