It looks like Madonna's new CD is going to have a short shelf life. In its second week in stores, American Life plummeted from No. 1 to No. 8 on Billboard's album chart with sales of 91,000 copies a 62 percent drop. (Luckily, she's got that acting career to fall back on.) In other chart news, 50 Cent regained the top spot, followed by the debut of American Idol Season 2: All Time Classic Love Songs (No. 2 with 101,000).
