Yet those same people who are not interested enough in music to seek it out in other sources are interested in debunking stereotypes for styles that they are unfamiliar with or simply don't care about?
Not all death metal is about guts either. But it's the stereotype. It happens.
Rap is about bitches and hos. Indie rock is about girls. Black metal is about Satan. Power metal is about flowers.
Nobody cares if not every band sings about those subjects. It's the stereotype and it's what's presented to the media. Why is a magazine or a TV network going to spend time pushing something that they know the average reader/watcher will instantly think is "gay?"
Also, another reason the extreme bands get a bigger push is because there are more big labels centered around those styles. Relapse. Earache. Nuclear Blast. Century Media. While Nuclear and Century have some power metal bands, by and large they are extreme labels. And guess who gives MTV the money to play their videos? Who has the resources to send out album after album for review? The big guys. The 'extreme' labels.
MTV and Decibel aren't trying to dictate the market. They're trying to dictate their pocketbooks. Can't blame them, but you can't say that they're responsible.
I don't buy the lack of exposure bit at all. Powerviolence suffers from 'lack of exposure.' Noise suffers from 'lack of exposure.' Ambient suffers from 'lack of exposure.'
Would they become instant media darlings if the right labels picked them up? No. They aren't accessible forms of music. It has nothing to do with America vs Europe, etc. They just aren't accessible.
Power metal is the same way. While it might be simple to us, to the average music listener, the music is complex. Too fast. Not enough dynamics. The songs sound the same. It's never going to be a fighting force in the music world.
Yes, I know not all death metal is about blood and guts. I was using what you said in your response and truthfully, a lot of it is about darker and more graphic subjects which is something that the kids enjoy. A lot why I think that is is due to the media pushing it down our throats, same goes with Ozzfest and Mayhem. In no way am I saying that they are the sole culprit though, but they do add to it.
I think what it ultimately comes down to though is power metal being lighter in mood rather than the death/black/thrash. Not with all metal fans, but a lot of them want their metal to be heavy and controversial as a way of rebellion. And like Jason said, the image does have a lot to do with it. The average young metalhead would rather listen to bands who are tattooed up, pierced up the giggy and in band photos look "scary" or "badass" than the power metal bands that usually look like just a group of guys with long hair who happen to play metal and worse, the power metal bands like Manowar who dress the cheese.
I agree with what you say about the labels. They definitely play a huge part of why these bands aren't getting pushes, and yeah, they sort of do own the genre at the moment. I'm not saying I don't understand their reasoning. It makes complete sense that these labels would go after the money instead of the risk of booking and signing power metal bands, but I still go by if more power metal bands were booked and signed, they'd be MORE popular...but not the hugest thing ever. That's not what I was saying at all. No power metal band is ever going to become instant media darlings.
Overall though, I think there is a valid argument about US vs Europe. The US in general, when we're talking all art-related industries such as music, film, etc. the most popular acts or movies tend to be American. There are exceptions of course, but labels or in the case of film, studios like to push Americans. In Europe, there seems to be a much bigger mix of bands, movies, etc. from an array of countries throughout the world and ultimately, they seem more open-minded, which may be why power metal bands have more popularity over there.
At the end of the day though, lack of exposure does hurt the genre. Again, I'm not saying power metal would ever be huge but it would be more successful with a little more exposure, much like other genres would be more popular with exposure. However, it will never happen.
