Just out of curiosity, will there be a demo any time soon?
Radiohead are an amazing band btw, one of the greats!
You should do the Radiohead thing and let people choose to pay for it when they download it.
I'd certainly pay (and did for In Rainbows).
Only trouble with that is that you can't decide how much to donate before you've played it possibly.
I've decided to operate on Australian time.
