I have a beautiful video that I put together and would love to share on various social media sites. I use music from the group This Will Destroy You in it. What is the easiest way to contact them to get permission to use their music for nonprofit sharing(Facebook) just for pure enjoyment? Any tips would be appreciated.

Contact the company that publishes their music (probably ASCAP or BMI).
