Yui is someone who used to have a thread at the old jpopmusic forum and now doesn't seem to have one at any place I'm familiar with. So I was rather pleased to see one pop up here.
I may break the habit of a lifetime and start a thread myself soon. I'm getting a little frustrated with yuku.com. It's difficult to use - and I'm increasingly unable to see the logic behind some of what is happening there. Thank goodness for jph!p.
Yui has done a lot of good stuff over the years. She's not my all time favourite anison artist but she's a real character and I've developed quite a soft spot for her. She seems fantastically self-sufficient. So, yes, I really thought someone should follow up on your initative.
I may try and dig out my copy of the "Nyanderful" PV because it's quite brilliant. In the mean time here's another old song I like, "Far Away".
