Whitney Houston fans have accused Apple of exploiting the late singer's death by increasing the cost of her in-demand albums on iTunes.
Her Ultimate Collection album, released in 2007, has increased by £3 ($4.70) to £7.99 ($12.60), according to entertainment website, Digital Spy.
It comes after the singer, whose most famous hits include I Will Always Love You and I Wanna Dance With Somebody, was found dead in her Los Angeles hotel room on Saturday afternoon at the age of 48.
Users reportedly complained they were unable to download the Ultimate Collection while it was given the new price.
Some music fans accused Apple of 'cashing in' on the singer's death, while others said the company should be 'ashamed', Digital Spy reported.
One customer said: '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 [know] that you will merely be lining some fatcat's pocket before Whitney's lifeless body is cold.'
Despite the increase in cost of her albums, the singer is expected to dominate the singles and album charts next week
She is currently top of the iTunes’ chart, with her 1992 smash hit I Will Always Love You.
