Plastic Beach peaked in second place on the LP charts, while Boyzone's Brother reached the top spot.
Albarn told MTV: "I was a bit f**king gutted that Plastic Beach only got to two in America. And I was obviously a bit gutted that it only got to two in England. Against f**king Boyzone!"
He quipped: "But at the end of the day it's okay. I've had a lot of successful number twos over the years."
Gorillaz release new single 'Doncamatic (All Played Out)' on November 22.
