Thanks for another great video Nicos. I’m actively recommending your channel to my junior team members!

Also, the word “genres” is pronounced like “John-raas” or “Dzshon-raas”. Please don’t take this as disrespect, I just want to help you out. In fact, I think your English pronunciation is otherwise excellent!
