Are these "happy songs with traditional instruments" useful for games?

hi!
I have made several songs using some acoustic traditional instrument I have bought around the world such as russian balalaika, peruvian charango, chinese lute, italian mandolin.

I was wondering if they could be used in game intros, gameplays, trailers, etc... their original purpose was not this one but who knows what a game designer may need!

They are quite "happy and uplifting" and generally structured as a "standard" song with intro/verse/chorus/bridge etc... they can also be looped.

if there can be some interest I will prepare them and submit to unity asset store...

thanks for you help!
