Whitney Houston's record label Sony has apologised for apparently increasing the price of some of her albums on iTunes after her death.

Houston tragically passed away on Saturday (February 11) and soon after, news spread that the prices of some of her material had increased on the UK iTunes store - by as much as 60%.

The internet soon placed the blame on iTunes owners Apple, but according to the New York Times, label Sony Music have addressed the situation and put the price hike down to error. They said:

"Whitney Houston product was mistakenly mispriced on the U.K. iTunes store on Sunday. When discovered, the mistake was immediately corrected. We apologize for any offense caused."

Nevertheless, Houston has been dominating the charts this week, with the UK iTunes store had at one point 38 Whitney Houston singles in the top 200.
