* CoveredUp:
** Listen to her cover of Peter Gabriel's "Darkness", then (if you haven't already), listen to the Peter Gabriel original.
** Depending on your taste, "Still Of The Night" originally by Whitesnake.
** Nightwish has rarely performed its own cover of "Over the Hills and Far Away" by Creator/GaryMoore since Tarja was kicked out of the band. Tarja performs it all the time.
* CrackPairing: Two thus far in her solo work.
** Tarja and Phil Labonte (All That Remains) - "Dark Star" on What Lies Beneath.
** Tarja and Justin Furstenfeld (Blue October) - "Medusa" on Colours In The Dark.
* FandomRivalry:
** "Tarjaholics" vs. "Anette!Nightwish". And, no, apparently [[FandomHeresy you aren't allowed to like both of them]].
** There is a small yet growing rivalry between Tarja fans and those of American band Evanescence. Evanescence singer Amy Lee Hartzler could very well be a younger sister of Tarja. However, most fans of one singer do not generally know of the other right away.
* LauncherOfAThousandShips: The more common version is the RealPersonSlash and/or HoYay version...
* LesYay: Tarja and [[Music/WithinTemptation Sharon Den Adel]] in the [[https://www.youtube.com/watch?v=Zim1Zp47m-c video]] for "Paradise (What About Us?)" They give each other [[MeaningfulLook longing looks]], smile coyly, stand really close to each other (to the point where Tarja's hair keeps blowing in Sharon's face)... And it all culminates in the two of them dressed in flowing gowns, holding hands and singing to each other.
** They have a ship name now - Sharja - and quite the fandom, with [[http://fc04.deviantart.net/fs70/i/2013/319/9/d/sharja_by_ariella_melina-d6uasq3.jpg fanart]], fanfiction... Anything and everything!
%%Administrivia/ZeroContextExample * ParanoiaFuel: "Lost Northern Star", from ''My Winter Storm''.
%%Administrivia/ZeroContextExample ** "500 Letters" from ''Colours in the Dark'', especially the whispered part near the end.
* SlasherSmile: Tarja shows a rather convincing one in the "Victim of Ritual" video.
