I hate it when I'm at the music store looking at CDs, and I pick up a potential buy, only to wonder if I already have the cd in my collection. Usually, when I think I already have it, I don't. I hate it when I actually buy the cd only to find that I already have it stashed and hidden away in my collection somewhere. I really hate it when I forget to return that CD within the return period.

This motivated me to create and use a DB, which keeps track of my CDs, and whether or not I have it ripped and stored on my empeg unit.
