This Saturday, Sunday Japan time, one of the biggest idols in JPop retired. In JPop there are a few big female idols in Japan that it has their career path and a very successful one at that. I speak of Mika Nakashima, Ayumi Hamasaki and Namie Amuro. Amuro-san is the one retiring. She threw one last concert in Okinawa(her home province) apparently, along with local artists it sounded like from the news. Her more notable songs are "Can You Celebrate?" and "Sweet 18 Blues" along with many others. I own both songs and definitely enjoy each of them. I wish I could remember more but it took the news mentioning them to remember.
Definitely give her a listen if you haven't.
