one song i LOVE live (especially more recently) is Ayu's "Boys & Girls". the music at the end is extended and I just love it! Especially in the MY STORY tour
I also like ELT's lives. Kaori's voice is so cute

She's a great singer <3 the old SPEED lives are fantastic, too. And more recently, Perfume have had some pretty great live performances, especially for an electronic group~
*i actually kinda dislike/get bored with Namie's lives...maybe because she doesn't have a very big connection to the audience...and she always looks down and never smiles! that bothers me a lot. it's like she never shows emotion--HOWEVER, her older lives are great because there's so much energy and stuff.
