Hehe I agree, even if of course it's a matter of taste at the end. Black Sabbath's Paranoid has been the album which made me want to know more about hard rock/metal more than 5 years ago. ^^
If you think Emperor are the best, you should listen them more! Kidding, but they're by far my favourite band - hard to guess, eh? Thanks for the request.
Cool :) Though I don't accept friendship requests from people I don't know, so if you want to talk to me or discuss music then you are welcome to do so and maybe I will add you sometime.
