This is how it works. Someone has to choose out of two bands that the previous post mentioned the one they like best, and then pit it against another band.
Example:
Slayer vs. Dethklok
If the next person chooses Slayer, then they'll pit it between another alike band (so we don't have stuff like Cannibal Corpse v. 50 Cent) like this:
Slayer v. CoB
Let's Begin
Children of Bodom vs. Cradle of Filth
