Requesting Permission

After searching for songs that fit the type of music video we wanted to make, we came up with three decent options.
The first song we found was 'Rough Cut' by Amber Rubarth. We found this song on unsigned.com.
The next song we found was 'Neopolitan Dreams' by Lisa Mitchell. However, this artist is signed to Warner Music Australia, meaning that permission may not be granted. So we decided to look for a third song.
The final song we found was my favourite, and is 'Corner' by Allie Moss.

We have requested permission for all three and are waiting for responses.
The email I sent to email on Moss' website is below.
