I hate the progressive death tag, despite the fact that Death, etc. are good and innovative bands, I hate that the genre tag lumps a band with a unique sound like Opeth in with all the bands that simply play generic death metal with a time signature change or something tossed in every once in a while. I think a genre is supposed to give you a faint clue of what a band sounds like, and if someone told me Opeth was a progressive death metal band, there's a damn good chance I wouldn't bother to check them out.
