I checked Amazon today and it looks like "music from Major Stryker" finally made it "on the shelves." Amazon is undercutting iTunes pricing ($9.99) and selling it for $7.99. They sell the individual songs at 89 cents.
If Amazon is going to truly give iTunes a run for the money, they're going to have to get the music into their store more quickly. Of course they do that for the artists who stand to sell a lot of product.
