Actually it's very interesting genre..
I've been listening all kind of music : Elvis, Stray Cats, Rainbow, Dire Straits, U2,....
And eventually worked as DJ 92-97. Never actually had enough time to listen old school metal, trash or death until recent 2-3 years with my son. Our latest finding is Kataklysm.
But my sons favorite is Nile as it has just amazing drummer

For me it's just a genre. And getting into a new genre is a very interesting trip.
What I want to say... in this world there is so much really good music.
You just need to find it by yourself.
It's hard to know who will be the next Elvis, Michael Jackson or Madonna. They all have something special which can't be easily copied...
But don't trust the tv, radio, record companies which are just doing the ->-bleeped-<- to get all your money making short time "idols"
