My Dad and his friend are HUGE music guys, I mean old music of course. My dad has a pretty big CD collection - app. 2500 albums (CDs). Now I've never been to his friends house before but just recently I went. He has a wall of CD's! I took about 20 minutes to get a rough estimate. I am estimating he has 26,500 CD's! By the way this is no exaggeration: next time I go there I'll take a picture...
That got me wondering; how many Gigabytes would that take up?
