just found another unlicenced use of track

I have no idea who composed this track, but today someone uploaded this https://www.youtube.com/watch?v=5AEqzIxyF4w with AJ watermark. Used by http://premierbasements.co.uk/

that sucks.

too bad there isn’t a way to contact the youtube channel directly or is there?

Enrolling music in Content ID through a service like AdRev would catch most, if not all, of these. AJ isn’t likely to do anything about it, but if in Content ID, you could possibly block the video or get the channel removed if it has multiple violations.
