Win7 Theme for Angel Beats?!

I finish Angel Beats! today, it is a story with sadness and a little happiness. It is hard for me to search theme of Angel Beats! because most of them had virus or my computer is32bit. However, I download it with cool picture in it. Honestly, the angel is pretty which make me want to watch more about it. I mean the plot is good too. I download the theme that has angel and a title on it. It's extremely cool and I like it very much. I hope there are second seasons for it. Angel Beats! (AB) has only 13episode. But there are cool and amazing event happen in these 13 episode. I think I will watch the next anime which has angel in it. I am going to watch a anime call "The middle of horizon". Joseph told me some plots in it which I think it will be cool. I have to study first so I have more confident when I am watching animes.
