Ever wonder why alot of music released over the past year or two sounds like crap compared to that from 5 years ago or more? Why listening to an entire CD of music that you otherwise like sometimes makes your brain or ears hurt?
Here's the clearest explanation that I've found to date:

Recording/Mastering engineers, stop producing crappy sounding music!
Of course, this insidious practice is how the music industry sucks us in to buying the "Remastered Gold Super Duper Edition" later on to cash in, when they simply could have done it right the first time.
