I don't often do this sort of thing, but this is a really great deal and it only lasts one day...
For a while AmazonMP3 has been offering some crazy good one-day deals via Twitter. I've gotten a few really good albums for almost no money, and today's is a really special one.
There are no hidden affiliate links or anything, it's just a really good deal worth spreading around.
Disclaimer: I think (but I'm not positive) this is a US-only deal. Also, if you're reading this after 2008-Nov-30 (Sunday) you're already too late, sorry.
