Actually, Rei that's only one of the many ways you can find your stuff! You can enter the UPC, the title, the artist, the actor, writer, and it goes on! Heh, I sound like a chincey car sales-man! ;D
It's good if you are bored and have nothing better to do!
I'm just lucky at finding these semi-useless sites!
Cool, artist! You /can/ submit the info for something that's not on there, but it's kinda... tedious to do. heh!
