True, Ayu is a busy busy busy person, but that's really not what strains her voice... She "screams" a lot in concerts. She really gets into what she's singing, and that has obviously messed up her voice a bit. It's like the "You were..." performances, except this has been happening for a while now. She needs to go on a complete vocal shutdown the day of each concert. The only time she should be talking before a concert is to do vocal warmups. I've heard of many singers doing this, and in the end, it really does help them.
