Ha ha well I suppose the price was good too yes! :O)
It's fine if you don't understand, really, you don't have to. I usually try to own a second, used copy I can listen to, but I won't open a rare, old album if that's how I bought it.
And I just find it beautiful to have an old sealed album, it's like being back in the 90s (when I was a kid that is, and barely knew what a NES was).
