Song choice for music video

I have sent the following email to various different people involved with Ed Sheeran.

"Hi, i'm Ben Smith, an A2 student that goes to Newport Free Grammar School, in Essex. I have a project in Media Studies where I have to make a music video for the song of my choice. This music video is non-profit and is just for educational purposes. We have a choice of finding a song that is not copyrighted or to get permission to use a song that is copyrighted. I'm a fan of Ed Sheeran, and thought it would be great to make a music video of his music. Therefore, I was wondering if it were possible for me to make a music video for Ed Sheeran's song "One Night".

Many Thanks, Ben Smith"

I have not received any replies and I am therefore now looking for lesser known artists for permission to use their song and hopefully, I will receive a reply from them.
