Before anything else, wow, somebody must've clicked a wrong check mark in the mastering software. I don't think I've ever heard a radio CD clip so badly. The fact that the normal broadcasts don't have this problem indicates the problem is the mastering engine..urr school dropout, and I won't even mention what level.
Special recording features Hosoya Yoshimasa (voice of Akatsuki Kojou) and Seto Asami (voice of Aiba Asagi) as guests, in addition to the regular personalities, Taneda Risa (voice of Himeragi Yukina) and Hidaka Rina (voice of Akatsuki Nagisa). It's pretty good except the sound quality is so bad, it's painful to listen to.
