ShakeSongs.com is part of the master's thesis of a student at the University of British Columbia entitled "Teaching Shakespeare Through Song." It doesn't look done - the links to Thesis and Forums both lead to "Coming Soon" pages. But still, it seems like an idea worth pursuing. Right now all I could find for audio links were on the "ShakeHits" page, using some sort of streaming player. Well that rules me out, I only work in MP3 these days so I can take them with me.
