I think the problem with people liking music is the fact that there are these 'categories'. Listen to what you like. If you are the person that listens to a Death Metal band, and then you think.... hmmm... I'm only going to like death metal! So you dont even listen to other bands. The fact is, you probably like everything else, except you lie to fit a certain group of people that you like. Your exactly like the kids that watch the OC and wear hollister.
Sonata Arctica is pretty good. I used to be more into them, but like someone else mentioned, I am kind of bored of that type of music because its just ...
power chord, power chord, power chord, power chord, power chord, amazingly fast solo, harpsichord keyboard solo, guitar/harpsichord solo, power chord, power chord, power chord, power chord, fade out.
I personally can listen to almost anything musically talented from Classical Music to Death Metal. I think the idea of being a 'metal head' is ridiculous and stupid. But hey, maybe im wrong and your all right.
