Query: Great album, awful mastering.

As the reviewer below pointed out, this CD has absolutely awful mastering. This is one of the worst examples of audio compression on a professionally mastered CD that exists, and it is disgusting. They have tried to make it so loud, that the music exceeds the limits of the CD, and causes clipping and the 'static' sound. I find this CD hard to listen to, which is such a shame because the music itself is excellent.
