My girlfriend's friend is really into Nickleback and from what I've heard it's incredibly emo and full of stupid. And Linkin Park's singer doesn't have that much range, he's not a very good singer...
They're a post-grunge band, they don't really have an emo sound to them outside of the lyrics.
They're pop/rock, and since when can't pop/rock be emo? Have you actually listened to their lyrics? They are a horrible band either way, and so is Linkin Park.
Please people, go listen to some real music.
