Interesting.
I personally find Katatonia's lyrics to be brilliant.
I can easily visualize all their lyrics, which I think is a good thing.
I love Katatonia, and I like their lyrics, but I'm kind of a straight forward guy for lyrics. I don't try to look for much meaning in the lyrics, so lyrics that make sense right away are more meaningful to me.
Most of the time I could give two shits less what a band is talking about in their lyrics as long as their music rocks.
Look at stuff that Mike Patton does. I've read that he writes his music to how the music feels. I love that.
