It is a known fact that music labels are greedy, heartless money machines. To confirm this, Ad Noiseam is donating a fix amount on each sales of its mp3 releases to Amnesty International.
By buying the legal, official mp3 version of an Ad Noiseam release on this site, you are helping the label support Amnesty International, who will get a portion of what you paid. This applies only to the orders placed through the Ad Noiseam webstore, and not to Ad Noiseam mp3 sold elsewhere.
