[@Buddha] That's fair enough, that verse calling out to other rappers was an important thing to his career. And maybe that helped give him some hype, in a similar way Hopsin doing a similar thing garnered him a bunch of popularity. The reason I say metal is the most expansive because it has tons of genres and influences many more genres on top of that. And has more concept albums that just push the bounds of "a collection of songs" that a lot of albums are. But I will say, I probably listen to as much rap as I do metal now...

As much as I'd freaking love a rap equivalent of Diablo Swing Orchestra or Haggard or Eluveitie, I don't think it exists. :c

Both genres honestly have a lot of similarities at least in public perception. They do probably have the most ways to vocalize the lyrics at hand. Metal incorporating all genres for vocalists and rap having a bunch of different flow methods and such. Often mostly criticized by people unaware of the genre, media saying it has connections to bad actions when most the music is harmless. When people claim to listen to everything, put on "the talky noise" "or the screaming" and suddenly want you to turn it off. Also rap metal is always a glorious guilty pleasure.

Also MF Doom is fun. :3
