My name's Vim Fuego (it's not really, but it's the name I contribute under at http://www.metalmusicarchives.com/), and I've been collecting music since the late 1980s, and have amassed a bit of a collection. It's mostly metal, but there's a bit of other stuff in there too. I'd suggest taking plenty of food and water with you, and definitely take a leak, before attempting this list, because it's kind of big.
And be warned: this list contains material some people may find offensive. Hey, it's a list of mostly heavy metal albums, so what would you expect?
How much of this embarrassingly large collection have you heard?
