To each is own. I will admit I can not understand everything. But there music is so good. If you remove the vocals and concentrate on the music you can see how good these guys really are.
That's why I listen to them so much, the music gets me going. And there acoustic stuff is great. They have some very nice ballads, which I think is where Eddie sounds his best.
Plus, they are not a commercial style band, they do tons of benefits, donations, among other things. With 8 albums released, they only have 4-5 music videos. There are groups today that have 6-7 videos per album. All they do it tour and make albums.
Also, you should reserve any comments until you have seen them live, you have a new found appreciation for them.
