Soon going to have to learn the horrors of CD Text, but thankfully I have ONE mostly commercial disk that seems to have it formatted correctly for my particular player.
Thankfully hydrogenaudio seems to have a good wiki page on it, and cdrdao will happily read the info out for me from the looks of it as well.
Just now realizing that pioneer units probably have the "best" CD Text support because the only people that ever used it heavily (I assume, citation needed) were DJs and most of the stuff I have that uses CD audio would be made by DJs soooooooo
