Want to buy music from Amazon.com on MySpace? Not so fast Most MySpace Music customers won't go searching for the obscure stuff . The big money is in pop hits. The industry's top 10 singles are all available to preview on MySpace Music — and they're all on Amazon.com's MP3 store as well. But that doesn't mean it's one-click easy to buy the music via MySpace. Trying to purchase downloads of 6 of the 10 directly from MySpace's new music widget failed. And those that worked required plenty of clicks and drop-down menus. [Idolator ]
