Nightwish - The Greatest Show On Earth (I've been a Nightwish fan since the early years and everything they do is amazing, but I've never heard a song this beautiful in my life. It brought tears to my eyes).
Iron Maiden - Blood Brothers
Type O Negative - Wolf moon, Die with me, Haunted, Christian Woman, World Coming Down, Red Water... basically everything.
Iced Earth - The Prophesy, Melancholy, A Question of Heaven, Ghost of Freedom
Ashes of Ares - The Answer
In Extremo - Die Gier, Melancholie, Liam, Gaukler (There's also an unplugged version of Feuertaufe floating around on the internet that's really nice)
Theater of Tragedy - Siren
Tanzwut - Stille Wasser
Leaves' Eyes - Ankomst, Freyja's Theme
Demons and Wizards - Fiddler on the Green
Avantasia - The Looking Glass
Gamma Ray - Valley of The Kings
Nine Inch Nails (metal enough, I guess) - Something I Can Never Have, A Warm Place
Rammstein - Nebel
Symphony X - Paradise lost
Pyramaze - Legacy in a Rhyme
Unheilig - Geboren um zu leben
Lindemann - That's My Heart (My brain has no clue what to do with Skills in Pills... I mean I like some really graphic shit, but most of that album is honestly the auditory equivalent of being puked on. And then there's this song. Classic Till...)
... I like some really sappy songs.
