Can those who love and listen to screamo know what the singer's screaming without looking at the lyrics at the first time they listen to it?
With some songs like heritic athem...but the song twist would be pretty hard to try to translate...
depends on who is doing the " screaming "
No, I do not think it would be possible to know what the screamo singer is talking about if you listen to the lyrics for the first time. It will need practice. This type of music is called hardcore punk.
Yes. As long as they're actually saying words.
