A fantastically trashy collection of cartoonish Europop, often so cheerful and upbeat that it's almost depressing ('Happy Boys and Girls' for example). The haunting vocal interplay of squeaky Lene and gruff Rene is something that you don't forget in a hurry, and the artfully-mangled English (almost the first line on the album is 'I've got a feeling you could use a little smile') adds to the goofy charm. It's actually quite hard to not like them - they don't seem to have any pretentions to being 'art' (unlike, say, 'Ace of Base').
The stand-out tracks here are the singles 'Barbie Girl', 'My Oh My', 'Dr Jones', and 'Turn Back Time' (which sounds extraordinarily Madonna-esque), with 'Happy Boys and Girls' and 'Calling Me' acting as solid reserves. Most of the other songs are fairly anonymous - 'In the Heat of the Night' is fun, but you'll probably skip the rest.
Given the band's inventive visual style, it would have been nice if the album had included the amusing videos, but you can't have everything.
