These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Tarja Turunen
Covered Up: 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.
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.
Les Yay: Tarja and Sharon Den Adel in the video for "Paradise (What About Us?)" They give each other 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 fanart◊, fanfiction... Anything and everything!
"500 Letters" from Colours in the Dark, especially the whispered part near the end.
Slasher Smile: Tarja shows a rather convincing one in the "Victim of Ritual" video.
The Rival: Averted with her successor Anette. Both women have spoken positive (albeit infrequent) things about each other at interviews and upon Anette's departure from the band saw her link to YouTube videos of Tarja's solo efforts favourably.
Yoko Oh No: Marcelo, her husband, is a male example, and Nightwish cites him as the reason they fired Tarja.
There's an interesting story about him - Tarja was apparently attacked onstage by a crazed fan in Guadalajara, Mexico during a concert in 2000, and was sexually assaulted. Allegedly, Marcelo had to save her, despite Tuomas' being right beside her, and then nobody in the band cared to check on her after the incident, so she was left crying alone backstage until Marcelo comforted her. This was apparently the start of Tarja's dissatisfaction with the band.
Here's an alleged eyewitness report from a fan who was there (note - this version has been edited to correct grammar/spelling, but the original can be found here):
"Okay, I was there (at the Roxy) in Guadalajara, Mexico. They had begun to play "Fantasmic", when a crazed fan jumped onto the stage and grabbed Tarja, embracing her passionately. The security guards and Marcelo intervened, with Marcelo pushing Tarja out of the way. Tarja either fell or was injured, and she threw her microphone to the floor and ran offstage for ten minutes. Tuomas then explained that they would be continuing onwards, even though it was obvious that Tarja was afraid (but she finished the concert anyways). For this reason, Nightwish cancelled their other concerts in Mexico, and Tarja was unwilling to appear before her Mexican fans."
