The group gave away its Radio: ACTIVE LP with the newspaper for free, prompting a 300,000 rise in circulation.
Speaking at UNICEF's Soccer Aid event, singer Danny Jones told DS: "It did 300,000 in one day!
"300,000 more than it normally sells. For us, that was just massive. If we sell 300,000 in a week, we've done really well. I'm really happy."
He continued: "I don't really care what anyone says, it was the right decision for us. We wanted to crossover our crowd and we had this amazing opportunity to get our album into millions of homes in one day and we took it."
Jones added: "We just want people to enjoy the album and realise we're not that band. In fact, we're f***ing amazing."
Soccer Aid airs on ITV on Sunday at 6pm. Jones will play for the England team alongside Jonathan Wilkes, Tom Felton, Craig David, Angus Deayton, Jamie Theakston and various ex-footballers.
