I'm rather happy that I paid nothing for the Radiohead album for the following two reasons:
1. It only comes in a 160 bitrate format, which is not up to snuff.
2. The actual album will include a lot more songs.
I've read in several places that this "revolutionary new approach to music vending" is actually more of a marketing technique, since the online product is crippled and incomplete.
That said, my free download is rocking my socks off, yet I feel no guilt. Perhaps it's the $30 I paid for my Radiohead t-shirt on the OK Computer tour.
