My advice: avoid vinyl, wait a re-release

I confirm the opinion of 2W - I (unfortunately) bought the vinyl without doing extensive research because I loved the Dark Knight soundtrack vinyl (great), but alas, three times alas, it is a catastrophe - the pressing is bad, and especially mastering is unworthy. The soundtrack has been compressed incredibly crude way, and all strong or fortissimo parts are completely saturated on vinyl - so it remains only the quiet parts of the disk that are audible (and my faith, pleasant, which makes the problem even more painful because there are only about 10-15mins quality on this disc is spread on 2 sides).
If you want to get an opinion, see the comments on vinyl editions on amazon.com and you will find that they are all (ALL) negative.
So: vinyl lovers - avoid at all costs, pending a vinyl edition worthy of the name
