Mm all I ever heard since I have memory was new age music (Enya, Era, Andreas Vollenweider, Vangelis, etc) because thats what my parents always listen to, apart from the pop music and national rock that are always playing on the radio. For one of those weird occurrences, when I was something like 13 or 14 y/o my older cousin gave my dad a Nightwish album for his birthday, and he played it in the car way home. He obviously hated it but I fell in love, it was so dark and beautiful and different from what I was used to. So then I started listening to Epica, Draconian, Summoning, Kamelot, Sonata Artica, Arch Enemy, Dimmu Borgir, Cradle of Filth.. Then Rammstein, Tool, Maximum the Hormone, Deftones, some experimental metal, other genres too like Dead Can Dance, Laibach, Siouxsie and the Banshees, Bauhaus, Swans, Nine Inch Nails, Placebo...
