Whitney Houston’s rehabilitation is complete. Her “I Look to You” debuts at #1 on this week’s Billboard chart with 305,000 copies sold. It’s the best Soundscan week of her career-not counting the “Bodyguard” and “Waiting to Exhale” soundtracks, on which she was a featured artist. Sales should stay pretty healthy, with what promises to be a quite revealing interview with Oprah airing soon.

Elsewhere in new releases, R&B singer Trey Songz debuts at #3 with his new album, while right behind him stands the Insane Clown Posse. Yes, folks, there are still a lot of Juggalos out there. Other debuts include Chevelle at #6, Pitbull (on the heels of 2 big singles) at #8, The Used (they’re still around?) at #10 and The Black Crowes at #12.

Next week, look for Jay-Z to crown the Billboard chart with “The Blueprint 3”. Of course, the Beatles reissues that came out today will sell big, although they will not be eligible for the Billboard 200 and will instead appear on the “catalog” and “comprehensive” charts.
