The German music group "die Prinzen" (the Princes, who incidentally have one of the worst websites I've seen for a popular music group) are of a genre that I'm not sure exists in the United States -- Pop Choir. Apart from (usually horrid) christian music, does anyone know of any American or British groups that are reasonably similar to die Prinzen? Bonus points will be given if they have biting satirical social commentary as their content. Songs particularly worth hunting down:

• Mann im Mond (Mann in the Moon)
• Millionär (Millionaire)
• Küssen Verboten (Kissing Forbidden)
• Fahrrad (Travel Bike)
• Alles nur geklaut (Everything's just stolen) (slightly NSFW)
