There are only two types of music, good music and bad music, they both trancend all genres.

I like some metal but my favourite band is boris who combine noise rock, stoner, doom and metal together.

This is a stupid thread... but that's a really weird conclusion to draw. I don't like metal much, but I'm not especially keen on rap either (by about equal amounts). I broke your argument. :P
Now guess what I like!

You're looking in the wrong places. There's a ton of material like that produced in the past two decades.

There's no fun in that

I doubt uulav would even know the difference anyway.

Now, i'm getting confused here. Maybe there's ton of material like that, but there's only one Ronnie Dio. His vocal was pure gold.

Well, if you just want to have fun, the choice should be quite obvious.

True. But there is nonetheless other good material out there produced in the past couple of decades. That's all I'm saying.

Hehe! Well, I was just semi-jokingly asking that, because in my experience people who hate metal, are usually rappers and vice-versa. Or at least they seem (to me) to be the most eager to trash the opposite genre.

Anyway...the genre you like? I'm totally going to rely on my conclusions / impressions as facts, and though I don't know much about you, here's something I do know:
1. Your avatar has a longhaired dude playing a string instrument, so that's gotta mean something
2. You're generous and light-hearted with your giveaways, which means you must be a hippie of some sort

= you enjoy rock music that's not too heavy, so I'd guess your fave band is Weezer. How right am I?

(please find a hint of sarcasm and joking in my completely unprofessional analysis=)

I don't mind metal, I like some tracks (even some of the heavier/darker stuff) but it's not a genre I listen to often because I've grown to prefer the more relaxing genres.

These days I mostly listen to ambient/chillout/psychil, but I'm also a big fan of video game music (if that can even be considered a genre), and I also enjoy the occasional drum'n'bass even though that a genre I mostly consider a part of my past.

Of course. I listen to most metal stuff (except for death and black, can't stand the vocal and blast beat). Anyway, i picked Rainbow as an example because they're perfect example to debunk OP claim. Heavy metal is the most tolerable genre from big metal family.

I'm betting on folk. ;)

Some like it more dark while others enjoy more light.
Stupid? Can't come up with any genre at all where you can't find "stupid" examples of it.
Not what you're looking for. Fair enough. You don't need to understand it, you don't need to enjoy it. It works for me, if it doesn't for you - shrug.

Still, there's no reason to actually "hate" it, just because you don't like it. Different preferences. Yes there are stupids out there thinking only "their" way is the right one, in any music genre. Why you join those too, only on the opposite side, is simply beyond me.

No, not because you're not listening to it. Because you feel entitled to tell the world instead of moving along and finding / enjoying what you like. Instead you lash out and bash it, ignoring that others feel the same way, just for a different music style.

And you tell us all of this, why?
