I think you need to clarify what you mean, mate..?
NOBODY is allowed to use my videos to enter open mic nor any other competition on any platform.
Besides, everyone in Open Mic knows who I am so if you were to try to pretend that it was your video they’d flag you severely.
If you can’t play music yourself then you can’t enter open mic at all.
Isn’t that right @luzcypher?
But are you wondering about the rules of open mic to enter your own self-made material? Then @luzcypher is the best person to ask.
