Their last album was #1 for a few weeks, but sales here aren't as good as in the past... Besides, we all know that if you're north american and you don't do good in the US or in Europe, you're doomed. That's why I'm shocked they're having another chance.
I read somewhere that they don't care anymore if they succeed or flop they just enjoy making music together, I really think that they don't care if they did , they would probably do something about it.
