asking permission

Sent an Email out today asking for permission to us A Little Opus by Little Comets for my music video

 Dear Sir/ Madam,

My name is Maddie and I am and A2 Media Studies student. My brief for the course work as part of my other all grade is to create a music video, CD case and poster for a song.

I would like to have your permission to possible use the songs;

• A Little Opus by Little Comets (Life is Elsewhere) 

The songs will not be used to make any profit for myself and will only be used for my academic work.

I hope to hear with you permission soon and thank you for taking the time t reply.

Yours faithfully.

Maddie McCollin

So far I haven't had a reply.
