CD-Text is part of the original Red Book standard and that information is
encoded in a sub channel. DVD players and some standalone CD players with
text display, notably many of those in cars, are capable of displaying
Some computer based CD drives cannot read sub code information, specifically
not all can read CD-Text and ISRC data.
Since sub channel information does not exist with MP3s, then the data for
titles, performers, etc., must be retrieved from another source, which is
either over the Internet via technology licensed by Gracenote, or from a
local database created by the iTunes user (for example).

Don't know of any, especially since some computer based CD players simply
cannot retrieve all of the data encoded in the sub channel areas. Some
certainly do, but maybe not enough players to justify what you are looking
for. And, until recently, many CD releases did not include CD-Text at all.
