grindcore is just boring ... bands with the lamest names ever, a cd with 50 songs with an average of 30 seconds, lyrics with such intelligennce and concept such as poop, puke, dead women, being drunk ... most of what I have heard sounds like a bunch of losers picking up an instruments, come up with the dumbest lyrics ever and play anything but something that sounds like music.
One of the few grindcore bands I have respect for are bands like Brutal Truth, Napalm Death, Jungle Rot, Leng'tche and some others although the latter do not really fit the actual grindcore sound or image.
