Naturally, the death of a popular musician or artist in contemporary times leads to a resurgence of their music in the industry, with album sales and (recently) singles downloads flying through the roof. This "rediscovery" of music, as many like to call it, almost always follows on the trail of the death -- a true schooling on the realities of the music industry.
Though a morbid enterprise, it has already sent Whitney Houston's music to high positions on charts worldwide just days after her death. Houston's album, Whitney: The Greatest Hits has soared to sells of over 101,000 copies by itself, this coming literally 3 days after the discovery of her submerged body in a Beverly Hills hotel bathtub as she awaited the huge Grammy event the next day.
Of course, speculation has run rampant: most are already convinced that this was the work of drugs, as Houston was known to have frequent incidents of abuse with hard narcotics. Authorities have not confirmed or denied too much at this point; they have not released the cause of death.
