The latest CD burning software has the ability to encode track and artist information onto a CD. It was pretty neat to put a new burned CD into my player (which is about two years old) and see the name of the song scroll across the front panel. For computer CD players like WinAMP, online track databases have been standard for years now. If you insert a commercial CD, the online database gets pinged for all the track information you desire. Of course it still isn't infallible and won't do well with custom CDs -- I inserted a teacher-burned CD of some final exam music (a Haydn string quartet), and the online database diligently told me it was "Schism" by Tool.
