Aloha !

Because they can't and are lazy ****ers who don't care about their fans. They hate to rehearse, so they don't do it. Sure they think about people hearing the same stuff over and over again, but they're so full of their own hits and how great they that they're forgetting that fans who've been with them for 5 or more years would like to hear something different.

So, lazy ****ers who just don't care.

Salaam Aleikum,
