Didn't think i'd get flamed so much :P

Brand New is my favorite band, and I doubt you could call them emo, the first record maybe, but Deja Entendu was really one of the best rock albums i've listened to in quite some time.

Taking Back Sunday is a good band too, I also wouldn't call them emo.

IMO the only band out of those four that could be classified as emo is perhaps story of the year. But, for the most part I would classify them with the exception of brand new, as pop rock. Emo is more like straylight run, or something corporate.
