Jay-Z famously told us he’s got 99 problems but a b**** ain’t one, but now we know for sure what one of those problems is: his app, which let Samsung users get access to his album early, is under investigation by US Federal Trade Commission after The Electronic Privacy Information Centre (Epic) requested that they do so.

"Samsung failed to disclose material information about the privacy practices of the app … and failed to implement reasonable data minimisation procedures," Epic said. They have also have asked, as part of the investigation, that Samsung "delete the user data that was improperly obtained" and, in future, collect only user data that is "necessary to run the app".

The Korean phone giants offered up a swift rebuttal, claiming, in a statement issued to the L.A Times, "Any information obtained through the application download process was purely for customer verification purposes, app functionality purposes, and for marketing communications, but only if the customer requests to receive those marketing communications. Samsung is in no way inappropriately using or selling any information obtained from users through the download process."

Magna Carta Holy Grail, which is currently the UK's number one album, was offered up to Samsung smartphone and tablet users before everyone else, as per an agreement between themselves and the rapper. This saw Jay-Z pocket around $5m plus other fees as part of the deal. However, these privacy issues combined with technical issues marred the experience for many users who, by all accounts, never had a problem with the traditional method of downloading tracks.
