Song permission

I have e-mailed rabid records, the record label who have Fever Ray signed to them. They referred me to this company:   http://www.d-e-f.com/ (which is an artist management company who mange artists like The Knife, Robyn, Moby and M83), who I then forwarded my previous e-mail to and they replied saying that I could use the song I had chosen as long as there was no commercial use. Below is the e-mail of the two correspondences.
