I'm not one who tends to listen to "popish" music a lot, so my appreciation of this album is a pretty good compliment. I particularly like the voice raised against unjust things done in our name in the first song. I think that as Creative Commons builds solidarity with other struggles, we will see an increasing number of politically critical media in the community.
Folk, hip-hop, rock, punk, reggae, trancey electronic, celtic ambience: this comp covers a lot of ground. I'd hesitate to say I could hand it to anyone and have them like at least one song; it's close, but it leans towards rock/folk/pop fans more than anything. All-in-all a great sampler of Creative Commons music.
