Whatever the reason is, there's no reason to get indignant about it. It's their choice - I don't know for sure that they did, but maybe their style evolved and they didn't think the first one was as good, maybe they redid the songs on it on a later one, maybe they just didn't like what they named it. What does that matter? If you like it, want it, and are willing to pay for it, then please do. Don't complain about it here though - I think I've made that clear elsewhere.
