gotta agree with the musical aspect of it. some of those riffs are mean as hell.
The singing is what really gets me though, you know? That screechy shit ruins good music for me.
I know it's not death metal, but an example I'm gonna use (since I'm assuming some here listen to Jrock) is Dir en Grey. Their singer sounds excellent when he, you know, actually sings. But recently, he's been doing this like, bloody murder screeching in his songs that totally cuts back on the effectiveness of the songs. And the sad thing is, all the other musicians are very talented too. But that's just one other thing that is sad about the musical scene, when one forces themselves to fit into a genre to attract a target audience.
I'M IN DESPAIR! THE DECLINING QUALITY OF INTERNATIONAL POPULAR MUSIC HAS LEFT ME IN DESPAIR!
