Last week, you could buy Radiohead's OK Computer in the iTunes Music Store. Not this week. No comment, no notice.

Wonder if the leaking of Hail to the Thief to the web soured Thom and the boys on the whole music download thing? If so, I hope it's a short term anger...

Also now absent: Sigur Ros. They had a headline in the Alternative section last week.

I hope I’m wrong about these artists pulling their music back. If this is just a temporary thing, at some point these searches should start returning songs and albums: Radiohead, Sigur Ros.

But this could be the backfire from Apple’s much-discussed negotiations with the five major labels: what happens if an artist isn’t consulted? I would bet, given how labyrinthine music contracts are supposed to be, that the label’s right to sell the music through online services might vary from contract to contract. It would be interesting to hear from the artists on this one. Maybe Moby could comment? (Only one of his albums, an old greatest-hits, appears in the store at present.)
