I'm Going to Need Another CD Book

So with my Zune Pass I decided to download every CD on my "CD's I Need to Buy" list. I'll listen to them all. Then I'll decide which ones stay on the list. So, I downloaded over 4000 songs in over 10 hours. They will all be expiring in a month so I've really got a lot of listening to do. I don't even know if it's possible to listen to that many songs because I suck at math. It was eye opening. I wouldn't have room for all those discs in my house. I'm going to have to put my collection on exam tables. It's going to be survival of the fittest: music edition around here for awhile.
