This is what happens when bands release the demos before the final product. Very little of the album is worse--it's just different from how you fell in love with it, and it can never be reversed.

Somewhat true. I like the demo of "Rain" so much that it did keep me from enjoying the new version. It's a shame, because the album version of it is really quite good. However, I have to say that the situation with songs like "Corazon" is that they made the songs worse.
