the term emo described a subgenre of hardcore punk which stemmed from the Washington, D.C. music scene. In later years, the term emocore, short for "emotional hardcore"
Carrabba's music featured lyrics founded in deep diary-like outpourings of emotion. While certainly emotional, the new "emo" had a far greater appeal amongst adolescents than its earlier incarnations.
.....I don't recognize that attribution. I've never recognized "emo" as a genre of music. I always thought it was the most Blue term ever. I know there is this generic commonplace that every band that gets labeled with that term hates it. They feel scandalized by it. But honestly, I just thought that all the bands I played in were punk rock bands. The reason I think it's so stupid is that—what, like the Bad Brains weren't emotional? What—they were robots or something? It just doesn't make any sense to me.
