Hi Andrew,

I'm so impressed your music in your Youtube Channel.
I'm Japanse and knowing your music from Drikin's youtube channel

His Channel

Drikin's videos are so nice but with your music, it's much better.

I just started my Youtube channel below.

Could you kindly allow me to use your music in my Vlog?

Waiting for your reply.

Many thanks!
