I'm in the camp that believes Julien-K news shouldn't show up either. It's not directly Linkin Park-related. It's just somebody that one member of Linkin Park collaborated with.
That being said, it's not my site, so I don't make the rules. I'll just deal with the fact that other bands' news may occasionally show up in the newswire. It's not like doing so makes less Linkin Park news.
