As stated in title, I'm planning to start a royalty free music project and I'm trying to brainstorm some ideas for how I can make music that would be useful to many people without making something that has been done a thousand times before.

My question to fellow composers and devs, what are some niche's for royalty free music that have not been oversaturated as of yet? Or else, how can I make something that will stand out from the rest of the pack?

Thanks for your help!
