What can we learn from Hitler and Hume?

In his talk on Algorithmic Art, Tom discussed the sales on his Hitler and Hume project. Tom used Mein Kampf as an input to music generation software and has put it for sale on Amazon and iTunes. Tom openly admits that ambient marimba and woodblock music is not a great musical innovation. However, he surprised me when he announced, "I'm selling nearly £25 a month of this rubbish at the moment. Vast majority EU, then the US. Grossed about £250… I have friends with actual musical talent who've sold less."

The interesting question here is: what are people buying when they buy a record from HItler and Hume?

Tom's discussion of his project made me think of some interesting posts I've read lately:

• How I Got a Blank Book to the Top of the Amazon Charts
• Are e-books the new content farms?
• The Kindle Swindle

Which is not to compare Hitler and Hume to scammy ebook publications. But, what's interesting is that 

1. Amazon is such a low-friction way of selling content
2. People who want to buy the Hitler and Hume EP are finding it (even if there are only a small number of potential fans out there)

I think this is, potentially, incredibly exciting.
