Copyright- starting point

So I can actually use the song I want to and my audience wants me to use I must first ask for permission to use the song from the record company to use and to let them that I am not using the song for any profit and personal just purley for my media studies music promo project, so at the moment I am searching for the record company's email or contact information so that I can get in touch in some way and tell them about what I plan to do with it and just ask if I can have their permission to use the song, instead of just doing it and getting in trouble for using it and causing both me and the company problems and issues.
