* CoveredUp: While not exactly the case, Mikael tends to name songs and albums after obscure progressive rock and metal bands of the seventies. Who honestly remembers bands named Blackwater Park, Still Life, Master's Apprentices, or Heir Apparent?
** Though the original is still far more well known, there's more than one person who is unaware that "Would?" was originally by Music/AliceInChains.
** While it isn't a cover, anyone who has listened to Camel's "Never Let Go", can tell that "Benighted" uses many elements from that song. This isn't surprising, as Mikael cites {{Camel}} as a huge musical influence on him.
* CrowningMomentOfFunny: [[http://www.youtube.com/watch?v=gRVDifmqW0E Mikael during this little speech.]]
** Even funnier than that, [[http://www.youtube.com/watch?v=onbOc4rePko they got pizza delivered on stage.]]
* CrowningMusicOfAwesome: While many fans dispute on which songs deserve the title, it is unanimously agreed by all fans that the epic title track of the epic ''Blackwater Park'' album deserves it. "Bleak", from the same album, is also considered an example by most fans.
** "Black Rose Immortal" off of ''Morningrise'' is a fan fave, most likely because you must be a true fan to make it through the song's ridiculous length.
** Of course, there's also those who take ''Ghost Reveries'', ''Still Life'', or ''My Arms, Your Hearse'' as their most epic album (when it's not ''Blackwater Park''). Hence songs like "Demon of the Fall" or "Ghost of Perdition" get a lot of love too.
* EpilepticTrees: Many speculate that Mikael Akerfeldt is one of the nameless ghouls in the Swedish hard rock band {{Music/Ghost}} (known in North America as Ghost B.C.). Some feel that he downright gave it away with the band's cover of "I'm a Marionette" by {{ABBA}}, as he's a huge fan of them (and has been known to wear their shirts during Opeth concerts).
* FanDumb: Has come out in full force after the release of ''Heritage'' and still had not let up by 2014. Many fans spend a lot of time whining about how ''Heritage'' wasn't a "real" Opeth album and that the band name should be changed.
* MagnumOpus: Generally considered to be ''Blackwater Park'', to the point where the band has been known to perform the entire album live.
* {{Mondegreen}}: There are lots of them, possibly due to the constant use of the MetalScream. "Deadly badgers made my wreath" (and variations, such as "Deadly badgers rape my dreams") in "The Drapery Falls", "Fresh made tacos of the earth" in "The Baying of the Hounds", etc.
* {{Narm}}: The awkwardly quick acoustic passage followed by the even more awkward drum solo at about 8:45 in "To Bid You Farewell", otherwise a massive TearJerker.
* NightmareFuel : The disturbing face appearing on ''Watershed'''s artwork. It is composed from pictures of the band's members.
** [[http://www.youtube.com/watch?v=cqcBD2oiEH8 "THE EYES! OF THE DEVIL! FIXED ON! HIS SINNERS!"]]*brutal guitar riff*
** There's also "The Leper Affinity". "Your gaze covered with virgin snow, Rigid features." Pro tip: it's about [[ILoveTheDead having sex with dead people]].
** The [[CarefulWithThatAxe scream]] at the end of Black Rose Immortal.
*** And pretty much the entirety of Black Rose Immortal in general.
* TearJerker:
** The closing track "Isolation Years", from ''Ghost Reveries''.
** "Hope Leaves", along with most of ''Damnation''.
** "Burden"
** "Black Rose Immortal" [[EpicRocking after around]] 9:40 and excluding the LastNoteNightmare
** From the same album, "To Bid You Farewell"
** And pretty much every other SurprisinglyGentleSong.
** The acoustic sections in "Dirge For November."
** A heavier example: the aptly titled "Bleak."
* TheyChangedItNowItSucks: Many people had this reaction to ''Heritage''. Gloriously inverted, however, with ''Damnation''.
