Hi Stu, the EX plays mp3 cd's so you can (as many of us have) download 12 or more audio cd's as mp3 data onto one cd giving you all the info in the main screen on the facia (Album names, artist, track titles etc) so you have at least a 12 album changer already installed.
Good luck, Al.
NB: if you have a separate cd changer it will not display the id3 tag info.
ps: I know there are a lot of programmes available but I found 'mp3 maker titanium' (made by MAGiX) to be very user friendly. Transferred my top 12 albums + a few singles from 'audio' to 'mp3 data' created a play list (make sure you prefix each album a, b, c, etc for the order you want them in) and download. I think it only cost £9.99 or so.
