Albarn said in an interview, "I'm making this one the most pop record I've ever made in many ways, but with all my experience to try and at least present something that has got depth."[3] He added, "I suppose what I've done with this Gorillaz record is I've tried to connect pop sensibility with ... trying to make people understand the essential melancholy of buying a ready made meal in loads of plastic packaging. People who watch X Factor might have some emotional connection to these things, this detritus that accompanies what seems to be the most important thing in people's eyes, the celebrity voyeurism."[3]
The first time Albarn went to Mali, he was taken to a landfill where he saw people "taking every little bit, a little bit of fabric to the fabric regenerators, or the metal and the cans to the ironsmiths and the aluminium recyclers, and it goes on and by the time you get to the road, they're selling stuff."[3] When Albarn went to a landfill outside of London to record the sound of seagulls for the album, he noticed a juxtaposition between the way the two countries dealt with rubbish.[3] "They've got more snakes... like adders, grass snakes, slow worms, toads, frogs, newts, all kinds of rodents, all kinds of squirrels, a massive amount of squirrels, a massive amount of foxes, and obviously, seagulls. [...] This is part of the new ecology. And for the first time I saw the world in a new way. I've always felt, I'm trying to get across on this new record, the idea that plastic, we see it as being against nature but it's come out of nature. We didn't create plastic, nature created plastic. And just seeing the snakes like living in the warmth of decomposing plastic bags. They like it. It was a strange kind of optimism that I felt... but trying to get that into pop music is a challenge, anyway. But important."[3]
Albarn says the album maintains a lot of the melancholy from Carousel.[3] He worked hard on making his lyrics and melodies clear on the album.[3] "Loads of orchestral stuff" was recorded but only a fraction made it onto the final album.[3]
