For every set of rappers presented pick the ones you like more than the other ones. Eventually you'll wittle it down to your very favourite, who will then appear in the "Found Favourites" section. Keep going to make a top rappers list of whatever length you like. There's no prescribed criteria, feel free to base your list on your own personal taste or who you think the all time greatest is or however else you want to do things. I know not all of them belong in the "GOAT conversation" but I wanted to include a wide variety. I'm 100% certain I forgot a few rappers of note here so let me know who I missed at: EMAILHERE
If you want a more detailed explanation, it works by keeping track of which rappers eliminate other rappers. Once those rappers are added to the found favourites list every rapper those rappers eliminated returns to the pool. This means as long as you pick consistently you should have a perfect list of who your GOATs are (and if there's one thing hip hop fans on the internet love its ranked lists). The pass button just keeps all of the current crop of rappers in the pool, so it's useful if you see a group you don't have an opinion about. Also, you can reorder your list afterwards by dragging the rappers around, just in case you made a mistake.
This is a full on rip off of the favorite Pokemon picker by Cave of Dragonflies. She put all the code on github for anyone to use so massive shouts out. The original idea was to make a better alternative to bracket tournaments. Those work fine for finding your one singular favourite but everything after that is heavily dependant on seeding (i.e. in a bracket if your two favourites are pitted against each other in the first round then one of your favourites even wouldn't even make the top 10). So anyway, I hope you enjoy finding your GOATs!!!
