As you all know, Opeth's first three albums were reissued some years ago with one extra "bonus" track per release. Why?? Were these outtakes, songs that Opeth decided to record just for the occasion, or what? I just want to know so I'll know if they're worth buying or if I should look around for an original copy somewhere on ebay. The only Opeth CD I own is the original release of Morningrise (without "Eternal Soul Torture") and I want to know if I have a real rarity or if it even matters.
