Permission to use copyright music [GRANTED]

After I sent an email to 'The Secession' in order to use their content, they have replied back allowing me to use their soundtracks as long as I add their credits to my video.

Music Copyright Permission

We will be mainly using soundtracks from a good studio called 'The Secession'. They provide soundtracks that can be used in trailers, films and commercials which would be more than suitable for our film.
However, their music was copyrighted. In order to use their music, I would have to contact them personally and ask for permission.

Firstly I went on their YouTube then clicked on their 'About' section and found their. website

 I then clicked on the 'Licensing' button and sent them a message here so that they could grant me a license to use their music.

I also clicked on 'Contact' which allowed me to send them a message to grant me usage of the music.
