Apple is coming under fire for raising prices of Whitney Houston's albums following her tragic death on Feb. 11.Digital Spy reports that Houston's fans are livid at the hike in prices of Houston's 'Ultimate Collection' on iTunes. Prices doubled within 30 minutes of the announcement of Houston's passing. Furious iTunes customers said that they were prevented from downloading the album at its original advertised price while the systems updated to show the new price.

However, reports suggest that Houston's publisher, Sony Music, is behind the price increase. One fan in particular was very heated, saying, "To say I am angry is an understatement and I feel it is just a case of iTunes cashing in on the singer's death, which in my opinion is totally parasitic. The album itself is great so please don't be put off purchasing it, just [realize] that you will merely be lining some fatcat's pocket before Whitney's lifeless body is cold."

Regardless of price hikes, Houston's songs have been soaring up the charts and will likely continue to do so, much in the same fashion as posthumous increased sales for Michael Jackson and Amy Winehouse. Houston's 'I Will Always Love You' is No. 1 on both iTunes' and Amazon's charts, and her 'Greatest Hits' album shot to No. 1 on iTunes the morning after her passing.

Leave it to the music industry to make a killing off of an artist's death.
