(Whoops~)
For me, there are some songs that I love ONLY when they're performed live, such as Boys & Girls. I get chills every time I hear that from Arena Tour 2005. ^_^ However, I hate it when Bold & Delicious is performed live. Although it is great to see her having fun on stage, I prefer her vocals in the CD track. It's hard of me to say I hate it because CD tracks are tweaked so much, so please don't hate me and go bashing me when I say this.
Also, I just heard A Song is born from Stadium Tour 2002. I cannot stand that song. I just watched it on YouTube? Wow. That was amazing.

Preferred recorded: (I feel so bad...)
Amazing in both ways:
And I can't decide for Memorial address.
