Just got round to listening to this, and found Disc 5 was faulty - skipped and jumped all over the place...
Universal Music kindly sent me a replacement; but this is faulty too!
Has anyone out there had similar issues with Disc 5?
Mine is fine...but my advice would be to just keep going until you get a good 'un. They'll probably get bored and send you a new set after a couple of attempts.
