Requesting Song Rights

As part of doing our music video, we had to request permission of the production company that originally produced "So Sick". We had to do this to ensure that no copyright crimes were committed.
First, we decided to look at an existing email that was sent by one of the past A level students last year. We analysed this template and used it as a base for out own letter to ensure the formality of the letter as well as to ensure we covered every point we needed to make. Although we most likely won't receive a reply from DefJam, if any copyright legal action was taken, it would clarify us knowing that we sent a permission letter

We started researching into the song of so sick on multiple websites and found that the label of the song was DefJam, which is where we started to search ways in which we would be able to send this email, we also found multiple other facts such as they have worked with the likes of Justin Bieber, Rihanna, Jay-Z, Kanye West and lots of other world wide famous artists. We searched on the website and we were unable to find their email address which made us look into multiple websites to find their email or a manager who we would be able to send it too.
We found that DefJam was owned by Universal music production so we looked on their to find someone or something where we'd be able to send out permission letter, this took us to a link that would allow us to tell Universal what song we would request for, however later on realised this was for the US. We were then relocated to the UK site, where we found an email address of a woman named Laura who was the leader of this sort of case.
