First consider this.
Are you watching for entertainment and enjoyment or for educational purposes?
For fun, videos of "drummers in a blender" videos are fun. Knock yourself out. Explore to your hearts content. You are subtly being introduced to the drummers world and mindset. Strengthening your emotional commitment to the drum set. Not a bad thing.
For educational purposes though YouTube is a minefield of misinformation. YouTube drumming videos often distort our view of what a drummers role is: accompanying.
Renowned drummer Terry Clarke said this of my drumming.
Now If I self critique my own playing I must acknowledge one of my main strengths: the depth of my repertoire. I know tunes. Zillions of tunes. Forty five years of professional music making I've had experiences in multiple genres. This deep knowledge of repertoire allowed me to play music with musicians above my level early on. Secondly, I practice mostly technique on the kit: Time, tone, and rudiments around the kit. With and without a metronome.
