Re X Japan I ll take another look and leave my comments on the talk page for the article But first I ve got a couple things that I noticed at the first look I ve got no problem with first party sources WP SELFPUB says that s okay As long as it s relevant and the article doesn t fully rely on them it s ok If you ve fixed the linking problem for every source that I had the first time I looked then you should be fine I know finding sources might be difficult but I ve done it before with another article that seemed even more impossible read Crush 40 that was nearly impossible to source the style section Also I seriously doubt you ll get enough out of the article for four samples cut it down to one or two and you should be fine as long as you write good fair use rationales and connections to the text You could work the samples into the history section but you d need to explain in the text how that particular song is relevant and the sample is used in an encyclopedic manner Best of luck I ll take another look later tonight I ve got some work I have to take care of first
