In regards to CD players displaying track info:
The CD has to have CD Text (data track), in order for a CD player that reads CD Text, to display it. I have one -- doesn't get much use though
Software on the other hand, generally looks it up on the internet, via GraceNote or FreeDB, using a unique disc ID, that is calculated by the program on insertion of the CD.
On my software, when you put a CD in, it will look it up on FreeDB -- when you load an MP3 or WAV into a deck, it will look it up on Amazon, so it can retrieve the album cover art, and display it. That of course, requires an internet connection of some sort.
Some software will read CD text as well, although it is generally of little use on a computer, IMHO, since playing an audio CD on a computer has far too much latency... YMMV
