The price of the singer’s Ultimate Collection jumped to £7.99 from £4.99 on iTunes, although it has now returned to the original price.
The increase prompted a torrent of anger on Twitter from the singer’s fans who described the increase as “greedy” and a “disgrace”.
Although Sony and Apple declined to comment, the price a paid for music on iTunes is typically based on the wholesale price set by the ultimate owner of the music.
Sony owns the rights to the back catalogue of tracks by Houston, who was found dead in a hotel room in Los Angeles on Saturday.
The 48-year-old New Jersey native had a well-documented history of drug and alcohol problems, but the cause of her death remained unknown last night.
Despite the temporary increase in prices, there was nevertheless a surge in sales of the singer’s music.
Ultimate Collection jumped to second in the UK iTunes chart, while Houston’s songs occupied 42 of the top 200 positions
