Thanks Cowboy_X. Following your link, I found there is a good FAQ/history at http://corporateanthems.raettig.org/press/

What a coincidence, I was just going through my MP3 archives and dug up some remixes... the story behind the corporate anthems website is even better. It started as a collection on a snarky British kid's weblog, but eventually KPMG sent a cease-and-desist warning that led to what might have been the first blog-community-driven Googlebombing. A bit like the more recent NPR controvery, but sillier.
