This is the new Eminem album on iTunes, 20 songs (well, if you include skits) for a pretty reasonable £7.99.

And this is the Deluxe Edition, which boasts a further three songs. £15.99.

And this is the same edition in physical form, with two CDs, all the packaging and uncompressed audio that you can rip into any format you want. £12.99. Yet if you want exactly the same record in digital format, you’ll pay £3 more than Amazon and £8 more than the standard album download.

Of course, it’s perfectly possible to buy the standard album and then buy the three additional tracks from the deluxe edition, bringing the total to £10.36 – but the point is that you shouldn’t have to. Somebody – presumably Eminem’s record label – is having a laugh at iTunes users’ expense.
