You explain everything so well, man. A lot of these RU-vid producers be making beats in silence without really explaining why and where they place stuff. Your videos are very helpful.
Not to discredit or argue with anyone.. but.. make beats that sound good to you. If you vibe to it, mostly other people will too. If the sound sounds good to you, use it. Make it how you feel and not on a “trap” template. That will make your beats unique.
