^^ Yeh good point. When I started learning guitar I actually found myself learning riffs and solos rather than chord progression stuff because they were too repetitive and boring. Being able to do that in some sort of meaningful way makes the music more challenging to the player and listener. But of course this leads to it being less accessible to the audience; hence the acquired taste I suppose. The most enjoyable music I have listened to of late is the symphonic metal as it is quite complicated and layered while still retaining a level of accessibility.
I don't think I hate death metal, I just usually find it annoying or laughable. But then again I suppose what I have been exposed to has been the try-hard stuff rather than the bands you listed. I see something similar in hair-metal. It was so lame and stupid but there was some great songs in amoungst it. But this was because it was accessible to the audience and was essentially pop music that was playing off of real metal.
Now hate describes how I feel about shallow vacuous pop music like Britney, etc and pop-rap.
