E! Online has this interesting tidbit about why Analog Heart was pulled from Amazon in April:
At the behest of Idol producers, Cook says he pulled the album pulled from Amazon’s MP3 downloads section last month shortly after topping the site’s charts, due to “fairness issues.”
Fairness issues? A-HA. I knew it was only because he was selling more than the other contestants who had albums out. Though it only sold about 1200 copies in its last two weeks on Amazon, this was apparently significant enough to cause the producers alarm, even though the voting was in the tens of millions every week.
If the producers were really interested in being “fair,” they should have blocked sales of any existing records by any contestant, but of course they couldn’t do that, because the vast majority of those had legal ties to other recording companies. Cook got screwed there because AH was solely his and the producers could lean on him.
