With Celine Dion's "Taking Chances" and Alicia Keys' "As I Am" poised to vie for No. 1 on next week's The Billboard 200, past album sales and current online buzz suggest the young R&B star could have the edge.

Nielsen BuzzMetrics, which measures blog trends, shows Keys generating the most discussion in the run up to the release of her album. As of Nov. 13, just shy of .03 percent of all blog posts mentioned Dion, while Keys enjoyed roughly twice as much traffic, with just under .06 percent.

Keys' previous effort, 2003's "Diary of Alicia Keys" debuted at No. 1, selling 618,000 copies its first week, according to Nielsen SoundScan. Dion's last studio outing, 2004's album of lullabies "Miracle," opened at No. 4 with 107,000, and her last pop album, 2003's "One Heart" landed at No. 2 with 432,000.

First-day sales numbers for the two albums will be available tonight (Nov. 14) via the Nielsen Building Chart. A recap will be posted on Billboard.biz.
