scrolling Mahler

I was startled on loading a new CD into the player tonight to see the words ‘Mahler – Symphony no. 9’ scroll across the display on the front. Not because the CD wasn’t Mahler 9 – it’s the newly released BBC Legends recording of the work conducted by Maderna – but because no CD has ever done this for us before. The tempo indication at the beginning of each movement was also displayed. Our CD player is about 3 years old. So I ask: have classical CDs only very recently started including this information in a form that a CD player can read? Or have we just happened not to buy any that had it? We buy quite a lot of CDs, but many of them are I suppose not new remasterings or pressings.
