The bonus DVD would be in my opinion can also save. It is shown the story to the creation of their album. Although I am the Beatsteaks opposite principle set postiv once, these recordings were of so unnatural and exaggerated wittiness that it was no longer funny. The studio recordings I found interesting, but the cutscenes with artificial (?) Interview and "soap opera style" scenes seemed very exaggerated and unreal (perhaps because they are a musician and not an actor?).
My conclusion: The CD is worth the 3 to 4 euros for DVD you can safely save (the money rather in the Beatsteaks DVD "B-side" invest).
