Asking permission for using my chosen track

Using the contact details found in Nao's (my chosen music artist's) Soundcloud page, seen below circled in red, I found the email of her General Manager, which was also in her official Facebook page.

I then composed an email to the her general manager asking permission to use her track and sent it. I did this because the song has copywright  protection which means it is protected from being used by others without permission, the copyright prevents people from distrebuting, copying or putting this work on the internet which would mean if i had not asked permission i would of been braking the law.
