I don't know why other reviewers think this sounds good, there is clipping, distortion, and hyper compression. In short, there are all the tell tale signs of loud mastering (see "loudness war" at wikipedia). For those that don't know, most pop rock offerings today try to be as loud as possible so that they will not be out volumed during ipod shuffle play. They do this by making the average volume approach peak volume. This means whispers become as loud as shouts. The end result is degraded sound quality and if you listen to the 1997 version alongside this one on a decent stereo or decent set of headphones, matching the volume levels, you will notice the difference. The new one lacks punch, has poor sounding cymbal crashes, no dynamics, and intermittent distortion. Overall, a poor job of mastering, but it's a good 40% louder than the 1997 version. So if you're thinking of buying this because you want the best sounding version of BTC, don't.
However, there are quite a few extras that are worth listening too, especially if you were lucky enough to score the edition that came with the live LP. I received two discs and one LP for 19.99, great deal. And if you are a long term fan this set is really something you should pick up. The booklet is 60+ pages and contains a few written pieces and lots of great pictures. The quality of the printing and paper isn't up to the previous standards of the last three sets, but compared to what one usually gets with remasters, it's great. The bonus material includes alternate mixes and versions, bbc live in studio material, b-sides, compilation tracks, and outtakes. The extra material is not as strong as say the Slanted & Enchanted luxe & redux stuff, but it is still worth while.
So five stars for the set and 1.5 stars for the mastering = 3.25 overall.
