Gorillaz's Plastic Beach: What do you think?

This morning Gorillaz kick-started their guardian.co.uk/music takeover by letting you listen to their third album, Plastic Beach. So what do you think? Is it a thrill to hear Mark E Smith collaborating with the cartoon crew? How do you rate the hip-hop cameos (Snoop Dogg! Mos Def!)? And is the whole "Plastic Beach" concept a decent stab at pop tackling climate change? It's been getting rave reviews already, but what do critics know, eh?
