There's actually nothing wrong with that. After I've composed my Top 50 list, and even after I've posted it all, I went to revisit it, and just found out I still love every record immensely. And if you think it's a damnable great record, you have every right to write this very thing.
And yeah, it really pays off to give your write-up a chance to blossom. Doing the first rough sketch of it (and sometimes the second and the third too, depends on the density of the record) and then transforming the thing into a bigger, more full, colourful and precise description is exactly what I'm doing when I write the review for that music magazine I work for. It's wonderful how a few more listens after the first draft of your text can enhance and naturally change your way of writing.
I think this thread wasn't meant for such posts though, so I apologize for the kind of offtop.
