Rage Against the Machine and Public Enemy come immediately to mind.
Edit: I guess those would fall into, what you call, “angry genres”. Not sure if that matters when it comes to spreading information. Popular is popular regardless of tone, and what is popular changes pretty regularly.
I’m a fan of Sinn. I’ve been lucky to collect a few watches over the past decade that most would consider “better” watches, but my Sinn 356 gets more wrist time than some of the bigger names.
