It's not surprising that Whitney Houston's death on Saturday would spark a renewed interest in her music.
What might be surprising, however, is just how much of a boost in sales that her catalog has received in the days since her demise.

Nielsen SoundScan has released sales data for Houston's music for the week ending Feb. 12, and the numbers are dramatic, to say the least. In overall albums, consumers purchased 101,000 copies in the week ending Feb. 12. That's quite the difference from the week ending Feb. 5, when 1,700 Whitney Houston albums were sold. Many more digital albums — 91,000 — were purchased than physical albums, which moved 10,000 units. (In the previous week, Houston sold 1,000 physical albums versus 500 digital albums.)

In terms of individual songs, consumers purchased 887,000 digital tracks, compared to 15,000 the week before. Of those, Houston's signature song "I Will Always Love You" was a favorite, with 195,000 digital tracks being sold, compared to 3,000 the week before.

And if you felt like you've been hearing "I Will Always Love You" on an endless loop on the radio the past few days, rest assured; you're not going insane. According to Nielsen Broadcast Data Systems (BDS), the song was played 2,137 times on all BDS-monitored terrestrial station between Saturday and Monday; during the same time period last week, the track was spun 134 times.
On Internet radio, Houston also saw a posthumous surge; Internet radio service Spotify saw a 4,000 percent increase in streams for Houston songs globally between Saturday — when Houston died — and Sunday.
