I've become way more open to all genres of music as I've gotten older, but metal will always have a place in my cold, dead heart :)

I'm exactly the same way. I do branch out and listen to some rap every now and then but metal is what I always return to. I think that for most people that the music they got into as a teenager will be the music they like the most for the rest of their lives.

But i suppose if we had to do a timeline for me it would be Glamrock in the 80's (because that's basically all there was) followed by an A-Ha / Depeche mode phase, which somehow lead me to the musical love of my life, which is metal. These days I have a hard time hearing about new stuff such as Slaughter To Prevail (which I had never heard of) so i'm glad you brought that up.
