The first sales week of 2010 could be another battle for No. 1, as "Britain's Got Talent" sensation Susan Boyle and "TiK ToK" singer Ke$ha compete for the top spot on the Billboard 200.

Early prognostications from label sources suggest that both Boyle's "I Dreamed a Dream" or Ke$ha's just-released debut album, "Animal," may sell around 100,000 copies by week's end on Jan. 10. With Ke$ha's very youthful audience going up against Boyle's more mature demographic, however, it's a tough call on who may come out on top.

Ke$ha's album has an attractive developing artist list price of $9.98, but it's on sale for less than that at the big physical retailers. Additionally, both the Amazon MP3 and iTunes Stores are offering it for only $6.99. Sources suggest that the album will have an overwhelming amount of its first-week sales powered by digital downloads of the set.

The 22-year-old pop newcomer has already made a lot of chart noise, as "Animal's" lead single, "TiK ToK," has sold 2.44 million total downloads -- including 394,000 this past week. It retains the No. 1 slot on the Hot Digital Songs chart for a third straight week as well.

A No. 1 position would be nothing new for Boyle, however. The singer has already clocked six weeks at the top with "Dream" and forced both Alicia Keys and Mary J. Blige to debut at No. 2 with their latest albums.
