I loved the songs, very catchy. There are no language issues, except for the 4 letter word meaning the "world down under". Even that is used quite rarely.
This is definitely a good listen, and if you like the whole punk/rock aspect, go for it. Again, there are pretty much no issues on the whole CD. DVD feature is a total plus, and enjoyable!
