I bounce around between most genres of metal. No reason to stick to 1 genre, you miss out on too much music that way.
Try Castevet. They're catchy enough for you but still have a solid atmosphere.
i don't really like the swedish school of heavier harmonised riffage with screamed vocals, it does nothing for me.
I try to keep an open mind, and I can honestly say that I do not dislike an entire genre of metal, but I stick with heavy/power, death (especially the fast and melodic variety) and black metal for the most part. I'm trying to listen to more doom and ambient/shoegaze black metal, but it's hard for me to find songs that hold my attention. I love Confessor and Drudkh, though.
