Hi - I won't waste your time. I used your song Isolated System in a Halloween display. It's not for profit, just the enjoyment of kids and their parents.

I keep getting a copyright notice from youtube and would like permission. I hope you like it and allow this. Your song is in the second half. BTW - Huge fan. Drove 8 hrs to see you guy's in Nashville for my son's first concert.
