Oh man, don't get me started on Katatonia! Omerta and Evidence are SUCH good songs... rest of the album is pretty nice too... not the kind of thing I listen to much anymore, but very fun, simple stuff! I'm a complete fanboy for this band! I don't even hear too much of the mallcore in Ghost of the Sun, it sounds like good old Katatonia to me.
Edit: Add to this list for me, all 5 Nightingale albums! I don't know why, and I don't listen to them too often, but when I do, I just love em! Ditto the 4 Unicorn demos and to a lesser extent their 2 studio albums.
