Much as they did after the deaths of Michael Jackson and Amy Winehouse, fans of Whitney Houston rushed out to buy the late diva's music in the wake of her passing on Saturday.

Billboard reported that Houston's only hits package, Whitney: The Greatest Hits, is poised to re-enter the Billboard 200 chart this week at #6 after selling 64,000 copies, according to Nielsen SoundScan. Most amazingly, that jump in purchases represent just one full day of sales, since the reporting week ended on February 12. Houston was found dead midday in Los Angeles the day before of as-yet-undetermined causes. The uptick for the Greatest collection represents a 10,419 percent gain over the pervious week, when it moved just under 1,000 copies. A number of other Houston albums also moved back up the charts, including her 1986 debut Whitney Houston, which jumped to #72 on sales of 8,000 (a 3,901 percent rise), the soundtrack to "The Bodyguard" (#80 on sales of 8,000, up 5,213 percent) and her final studio album, I Look to You (#118 on sales of 5,000, up 3,901 percent). The magazine reported that more Houston albums were purchased in the last week — over 101,000 — than had been sold in all of 2011 and 2012 to date. The most impressive figures, though, were the number of digital tracks fans purchased. In all, there were 887,000 downloads over the past week, a gain of 5,730 over the previous week's 15,000 tracks sold. The biggest gainer was, of course, her signature song, "I Will Always Love You," which moved 195,000 units, a 6,742 percent gain over the previous week. While that song enters the Digital Songs chart at #3, seven other songs hit the Digital Songs chart as well, including "I Wanna Dance With Somebody (Who Loves Me)" (#25, 74,000, up 8,769 percent), "Greatest Love of All" (#32, 60,000, up 7,270 percent), "How Will I Know" (#46, 43,000, up 5,767 percent), "I Have Nothing" (#53, 38,000, up 5,179 percent), "Saving All My Love for You" (#65, 33,000, up 6,423 percent), "One Moment in Time" (#74, 30,000, up 6,206 percent) and Houston's rendition of "The Star Spangled Banner" (#75, 29,000, up 8,278 percent). Next week's chart should see an even bigger boost to Houston's catalog as it will reflect a full week of sales.
