Research - Copyright Clearance

During the summer holidays we were told to do research on the songs we would potentially want to make a music video too. Then we had to send copies of copyright clearance to the record label companies to gain permission to use their music videos. The songs I considered included Don't Go by Wretch 32, Somebody that I used to know by Gotye, A-Team by Ed Sheeran and Someone like you by Adele. However only two companies got back to me. Here are print screens showing the copyright letters I received from Ministry of Sound and Creative Vibes.
