The guitar work in some of the songs is utterly mindblowing, another reason why i love it, while panteras lyrical smoothness may be comparible to running your face along sand paper, their music itself is really good and well constructed. Lately, i'm finding myself more into thrash metal and industrial stuff, both fairly contrasting, but both, in my opinion, really really good and very rewarding to listen to, not to mention, energetic and uplifting. Some of the lyrics can be awful, as with all music, but some of them i find are really awesome, exodus for example have some great lyrics...
I will agree however, that cannibal corpse are utter shite... Speed core metal just sounds like someone grunting into a microphone while you have someone on the guitar having an eppileptic fit
