The Australian psych rockers, whose second album "Lonerism" will play London's Hammersmith Apollo on June 25.
Reacting to getting the Number One slot, the band's Kevin Parker said he finds it difficult to be completely satisfied with his own work. "You never really finish an album," he says, "you just run out of time."
He added: "When you're making an album, it's very difficult to still be in love with it at the end in the same way you were when started it. By the end of 'Lonerism', I was doubting everything. I worked myself into a state of mind where I was questioning everything."
As NME notes, he also said he now believes the album is his best work:
"I had that moment with every one of the record's songs where I'd feel like it was the best thing I'd ever written. I still think it's the best bunch of music I've made so far."
