Asking for music permission

I would like to use certain songs from artists that are signed to a label in my music video however I will need to try and get permission from the artist/record label therefore I will need to email them to see if this is possible.

Here are screenshots of my emails requesting permission to use electronic music from the label Ellum Audio and music from the artist Childish Gambino. If these get accepted then I may choose to use this genre of music in my video.
