1) You can never really discuss music over the internet. Just forget about it. People will always have different opinions regarding it, no matter what genre or sub-genre. It'd say any day that I generally dislike trance or techno, but there are obvious exceptions - but basically I prefer guitars and that kinda direction a lot more (rock and heavier, or softer) in general. I still do respect people that have the opposite preferences in music. Also, it'd say you can "discuss" it when it comes to saying which stuff you personally prefer, and why. But agreeing which is good from an objective aspect is the same as continously banging your head against the wall.

2) Discussing whether or not X band is either nu-metal, alternative rock, heavy rock, or whatever is just as lame. People will never agree.

I personally admire Iron Maiden and consider them very groundbreaking for their genre, however I see why a lot of later generations of metal fans don't admire them as much as other people. In 10 years bands that are innovative and do great quality music now will be neglected and not praised as much, simply because people haven't been around to experience them by then. The hyping isn't up to par.
