Apologies for unsubscribing.
I'm somewhat obsessive compulsive about the number of subscriptions I have.
It must be divisible by three and it wasn't when I was subscribed to you.
I still appreciate your music, as well as the huge amount of effort I know goes into a lot of your videos and will probably continue to watch them - just as an unsubscriber now.
Wish you all the best!
1) That's weird.
2) If you hadn't told me I wouldn't have known and there'd be nothing to apologise for. (And there still isn't tbh, you can use the site how you want!)
3) I have (at least) 3 channels - make up the numbers!
4) Having unsubscribed, they had 61 subscriptions, which clearly does not divide by three.
