I'm going to show some of my notes (the exact words on the paper) that I wrote down one of the days before I made my decision that Ai Shinozaki was the Best Pop Singer of the First Half of 2012.
This was a very difficult decision and the last week or two was mainly between Ai Shinozaki and Ne-Yo. They were going to tie, but I promised there wouldn't be a tie and there wasn't by the time I finished comparing their singing/vocals.
