I just had an email update about the Radiohead album that I ordered. The download is available from tomorrow. I had concerns that it would be in some locked-down format that I might not be able to play on Linux, but...
THE ALBUM WILL COME AS A 48.4MB ZIP FILE CONTAINING 10 X 160KBPS DRM FREE MP3s. (their caps)
Shame it's not Ogg Vorbis, but you can't have everything. I expect it to be on the file-sharing networks withing seconds of being available. Personally I wouldn't care if it had watermarking to identify who bought that copy. That sort of protection does not infringe on my ability to listen to the music how and where I wish, but would identify those breaching any restrictions on sharing.
I shall report further when I've had a chance to listen. It's LUG tomorrow night.
