This is like asking for recipes when you like milk.
Work yourself through the most popular bands of every sub-genre, that sounds appealing to you. If you found, what you were looking for, dig deeper and listen to whole albums. There is much good metal music for acquired taste, filling niches and exploring extremes. The most popular songs of bands often misrepresent their usual style, regardless if metal or not.
Uh, I didn't want to write that so harshly. With the large variety even within this genre however recommendations will inevitably go unheeded.
Anyways the albums that got me into metal where "Once" by Nightwish (melodic metal, a style of music I could even enthuse my parents for), "Iron"/"Ensiferum" by Ensiferum and the "Nordland" albums by Bathory (both folk/pagan/viking metal). (see >>552
The best way to find out what you like best is to learn the history of metal. Listen to the original bands, then move on to the sub-genres that started to appear in the 80's and 80's. I'd highly recommend Black Sabbath as a place to start, seen as they created heavy metal.
