Great album if your child understands why bad language really is bad.
This album contains some really catchy hooks, riffs, and vocals that you would most likely sing-along to if not for the often used swear words throughout the album. There are songs like Let Yourself Go or Kill The DJ where there are over 10 f-bombs dropped but then there's a lot of pop-rock anthems like Oh Love that are just 100% clean and good for anyone to listen to. The swears are basically the only reason this album might be considered "explicit" for a lot of people, but I don't think it should be such a huge deal. I have personally been a fan of Green Day since I was about 7 and I know how bad bad language is and so I avoid using it. That is why I think you should know your kids, you could talk to them about what they think about why bad language is bad, why would they use it, and if they understand all that then I think they should really listen to Uno because it's just a really great album full of awesome puck-rock songs like Loss of Control or Angel Blue.
