What is so special about Judas Priest's "UNLEASHED IN THE EAST"?

Judas Priest are iconically important, but honestly they don't have a whole lot of songs I like. That's not to say I'm dissing them, because I highly respect them for the amazing musicians that they are, I just have trouble getting into that sound. I've always been more of a Black Sabbath-sounding fan I guess. No offense meant.
