Houston headed to top Billboard Top 200

Whitney Houston struggled with her voice during her much-hyped comeback performance on ABC's "Good Morning America" on Tuesday. But industry prognosticators are suggesting the soul music diva won't trip up on the charts next week.

Released on Aug. 31, "I Look To You" - Houston's first album in seven years - is expected to sell upward of 200,000 copies, which should easily enable it to debut at No. 1 on the Billboard 200 chart. If this is the case, Miley Cyrus' "The Time of Our Lives" exclusive Wal-Mart EP, which entered at No. 3 with 62,000 copies sold this week, according to Nielsen Soundscan, will drop down a few slots below Houston's "You.

With a chart entry like that, Houston won't need to apologize to her fans, although she did find herself asking for forgiveness from the 5,000 concertgoers in New York's Central Park on Tuesday for overusing her famous pipes. "I'm sorry. I did 'Oprah.' I've been talking so long... I talked so much, my voice," she attempted to explain. "I shouldn't be talking, I should be singing," she said before breaking into "I'm Every Woman," the last of her three-song set.

Other tracks performed included "Million Dollar Bill" and the album's title track, during which Houston choked up.
