If someone wants to, they can draw lines between Punk and Metal. This is Punk, this is Metal. And then do the same with each band, this band is more punk, this band is more metal, etc etc.
But you don't have to do that. Grunge was one of many types of Punk-Metal. It becomes much much easier when you do it that way.
