Agreed. Sometimes a band...like (I think) Between The Buried and Me....really captures me.....until the cookie gurgling comes in...and I lose all interest. *FOR ME*...there's nothing musical or musically interesting about it at all. I get the feeling these bands often do it because they can't sing.
I still like growling/screaming vocals a lot. As long as their is something interesting about them. Some guys are good at it, others....not so much. And personal taste matters as well.
However, I'm finding myself more and more wishing some bands would move away from it as well. Their music, while crushingly heavy, doesn't really need/fit with screamy vocals IMO.
I was just listening to some Periphery at work today and actually found myself thinking on some of the songs, "I sorta wish he'd just sung that one" while on other songs I liked the screaming stuff.
Lots of it is personal taste I know, but I don't need screamy for it to be heavy, but I still like lots of screamy stuff. If that makes any sense at all.
