I remembered a discussion about why kanariya was never performed live (conert/tour and unpublished performances), and I noticed some others that were never performed either.

I didn't include the 2005 songs (so far alterna and Will weren't performed, but they're new) and I wasn't sure if most songs from MY STORY counted because they're kind of new (almost a year).
So, was it just because some of these songs weren't popular? I was just wondering what the deal is.
