There are some extraordinary IT Anthems at ZDNet (link from MeFi). Most are just parodies of current songs, but there are a few specially-composed songs, most notably the venerable Ever Onward IBM.
They are all utterly cringe-worthy, but to be honest, not any more so than the school and college songs I had to groan along to. Sadly neither the Carmen Berkhamstediense nor the Carmen Petrinum are available on the web, but take it from me they have more weak puns than a kid’s joke book, and a fair ton of synthetic enthusiasm. Plus, they’re in Latin!
