You might be right. I don't know anything about how the deals made by Amazon or Walmart work. But, you have to understand how dire the situation is for recorded music. According to Wikipedia, the Buckingham/McVie album, which I thought was pretty good, sold 22,000 copies in the US in its first week, good enough to debut in the Top 20, where it peaked. But, because most people don't want to buy music, that's only about $330,000 in total sales (assuming $15 per album). Nicks' one sold out show at the LA Forum on the other hand, grossed $1,379,531. A FM show at the LA Forum would probably gross even more, perhaps $1.6 - $1.8 million. We might both be right. She might just hate working with Lindsey except on tour. But, there are financial incentives for playing as many live shows as the public is willing to pay for. It's why the Stones, Guns n' Roses or the Who continue to tour without releasing new music. It's sad because we many never know if they are tapped out creatively, or whether they could have made a great album if they took time off from touring and worked on an album for a year the way people used to.
