Green Day famously penned their 2004 album "American Idiot" to denounce then-U.S. President George W. Bush - which has subsequently been made into a rock opera.
However, Billie says fans cannot expect a follow-up about President Donald Trump because he's too angry to write songs about politics at the moment.
"It's not that I'm ignoring it, it's just that the current political climate is something I just can't draw any inspiration from. I've got tons of feelings about it," he tells The Guardian. "I think Trump is a piece of s**t. I think (Senate majority leader) Mitch McConnell is pure evil." "All they care about is looking after the rich and they don't care about the common people. But I find no inspiration there. It's so depressing. It's hard to dance when you can't get out of bed."
Drummer and band goof Tre Cool says that even when the band got political they used to try and promote unity - something that feels distant now.
"And the world has become so divisive," he adds. "We wanted to try to bring people together. It's become something of a far-out concept to love each other!"
Their new album "Father of All..." is out now.
