I've found an interesting petition at http://www.change.org/petitions/stop-the-loudness-wars-and-release-high-definition-music-downloads
I found it via a thread at diyaudio.com.
"Music gives many people enjoyment, but the dynamically compressed albums available today are short changing people of this enjoyment.
As music lovers we are fed up with the high level of dynamic compression used on albums available today and would like to see the immediate introduction of “HD / Unlimited” music, where the recording has not been dynamically compressed and has been optimised for sound quality.
We believe that this is the way forward to reintroduce people to music the way it’s meant to sound. The technology is there, I’m sure the demand is there, Record Labels make it happen!"
Sign it and join the movement. There's also a Facebook group, make sure to join it as well (if you have Facebook).
