hey fluffy, you can interpret the categories however you like! they are intentionally kinda vague with no set meaning, so you can choose something that feels kinda related to the words (like perhaps 'brain tech' = 'how technical it sounds'? does it tickle your brain? up to you though!), or if that still feels too overwhelming, you could vote the same thing across all 5 categories
you will be surprised how there end up with clear and usually understandable top dogs in all the categories at the end, even despite this vagueness
