I had a library that was nearly 5GB, but I only managed to pull roughly 2GB (which came out to about 25 CD-R's).
I did copy the original list over to Excel, so I'm marking off what I have, and then leaving up to the Internet to find the rest--as I cannot hook up with my buddies from Stout and Redux the songs.
2GB, wow.
I used to do radio when I was in college, which is where I got most of mine from, but the cds didn't belong to me so I couldn't take them with me.
