I never realized that she didn't like endless sorrow. I thought she just said that she thought the album was too depressing so she made a 'happier' version of it for the album. I personally enjoy the original one. I thought it was raw and full of emotion.

I do agree that NEVER EVER is missing something. Although it's one of my favorite songs, I sometimes feel like when I'm listening to it...somethings missing. I dunno I guess that's what Ayu was thinking.
