Eminem's fifth straight No. 1 debut, "Relapse," roars at the top of the Billboard 200 with 608,000—the biggest sales week of the year for any album and the best since AC/DC's "Black Ice" began with 784,000 copies last October . . . The rapper was just one of many acts who had a new album arrive last week. Those that open high on the Billboard 200 include Kenny Chesney, Method Man and Redman, Dane Cook, Busta Rhymes, Tori Amos and Kate Voegele . . . The two-night finale of "American Idol" last week impacts this week's tallies, as both winner Kris Allen and runner-up Adam Lambert storm the charts.
