Mütakrüde is a heavy metal band that Molly listens to. It has been mentioned in multiple episodes.
The Tough Customers listened to the band's new album in "The Law of the Jungle Gym". Molly suggests that Brain should play their latest album "Shinsplitz" in the ice cream shop in "Breezy Listening Blues". The CD was not in stores yet, but she received the CD from her friend's cousin who knows the ex-drummer. In "The Agent of Change", Agent Double X listens to Mütakrüde as well.
