Lol, I hate Rap, R&B, Country and Pop the most. So I guess they'd be silly forms of music for me, lol.
But, I agree with Aussie, Christian Death Metal is pretty silly. Really, that screaming type of metal(the type where you can't understand a word the vocalist is singing) is silly. The music might be alright, but the vocals just stink in my opinion. I like the type of Rock music where I can actually, ya know, UNDERSTAND what the vocalist is singing. Otherwise, it seems kinda pointless for me to listen to it.
