I believe this release it will be the way of the future. The CD single is no longer relevant to the point where singles charts are now being replaced by downloads charts. Full length CD's won't be too far behind. No more having to pay for printing artwork, no more having to chase down distribution agencies or commissions from independent music stores. I'm still not sure how I feel about this. I love the artwork, liner notes and the bits that usual go with putting a piece of music in the market place. But it does make sense, particularly for a well established act such as Radiohead, to do things this way and save themselves a heap of hassle. And putting the onus of cost on the consumer is a novel approach to selling their music.
