Who turned the knobs? My deaf grandmother, it could be better!

First of all, the music of Imagine Dragons is great. Radioactive one of my current favorite songs. It's also super time. The CD is quite varied. For 5 star. I'd like to enjoy. But ....
The production is so grottig, not even the Sex Pistols had as 'punks' a so miserable
Sound quality. The Loudness War takes in this 'production' harrowing forms. As are all deaf?
Has not the result (your original CD on good conditioning) belongs?
With Radioactive I first thought my Bose system was broken. Therefore immediate comparison with another CD.
Result conditioning throughout (so far so good), CD sound quality? Disaster. Not completely overridden-actually audible.
What shoud that?
For the Music 5 star; Production 0 stars = 2.5 stars rounded up as. 3
