This topic reminds me a quote from Max Planck about the adoption of a new scientific model:
"A scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it".

Hello. Have you visited jamendo.com? You can filter searches by tags and license. I downloaded great music with Creative Commons Attribution License. One more tip, search musictrade in mininova.org, you can find the music from musictrade.info in Creative Commons Attribution License, many of them in FLAC 24-bit format, I like particularly the Lena Selyanina's piano music.
I hope you find it useful, if you need more details, tell me.

Apathetic, euthanasia... very good inputs, Minor. Thank you.

Thank you Jan, your comment is very helpful. What about religions, governments and other powerful groups?
Does anyone else want to comment?
