How so? Screamo not being a genre, or the two subgenres I named?
While Screamo is not a mainline genre, it is in fact classified as a sub-genre. Wiki article:
I honestly hate Country. Every single song sounds the same. Not only with the same temp, but the singers sound exactly alike. Simply bunch every country song together, and you get one really long, boring song.
Read the last sentence in the first paragraph under "Vagueness and Misuse of the Term", should be a quote. That should explain why I and most people I know don't consider it a genre.
