The emo bands discussed in this thread are part of a genre that came out of the Washington DC hardcore scene. They have nothing to do with the pop bands that have had the word emo attached to them by marketing executives as a promotional tactic, and anyone who refers to themselves as an emo almost certainly listens to these pop bands rather than the music this thread is about. They have nothing in common. So for the purposes of this thread;
Not emo: Bullet For My Valentine, HIM, Panic At The Disco, My Chemical Romance.
Emo: Rites of Spring, Moss Icon, Embrace, The Hated.
