Susan Boyle's "I Dreamed a Dream" continues to rule the Billboard 200 chart for a fourth straight week as it sells another 661,000 copies. The "Britain's Got Talent" contestant's reign blocks Alicia Keys' from gaining her fifth No. 1 album, as her "The Element of Freedom" starts at No. 2 with 417,000 ... As for next week, industry prognosticators indicate Boyle will probably continue to sit pretty at No. 1 with possibly another 500,000 in sales. Meanwhile, Mary J. Blige's "Stronger With Each Tear" will be the chart's top arrival, perhaps starting with around 350,000 copies.
