CD ROM

I have a lot of CD and CD-R. They are software for CP , music CD, and game software. Since I put them in the bookshelf together, it's hard to find the CD which I need. Today I cleared off the bookshelf, and put CD in order.　Of course　I cleaned each genre of CD up to different boxes. It took 2 hours to do that. Although I was so tired, I'm going to sleep.
