Letter of consent for song

In order to be able to use our chosen song, I remembered that we needed to ensure that we had consent from the record label of Ne-yo and so we ensured that this was finished early. His recording studio for the song is Def Jam and so we researched the contact details for this studio so that we could send a letter of consent. This was difficult however, as we struggled to find an e-mail address and so with assistance from Miss, we looked into the contact details of Universal who is the parent company to Def Jam. Within this research we found an e-mail address of a lady who's contact details also came up when researching Def Jam initially. We then agreed that this lady was the correct person to e-mail and so we used a template to type out the letter and send it to the e-mail address. If she does not reply then we are fine to use the song as she has not replied negatively to say that we can't. This would be the only reason why we wouldn't be able to use the song but we hope that this will not be the case and so for now we will continue with this record.
