       As Escient has changed the terms of licence for accessing CDDB, some
 programmers complained that the new licence includes certain terms that
 threatens them in a way they cannot accept: If you want to access CDDB, you
 are not allowed to access any other CDDB-like database (this one, for
 example)

           Gracenote  
       Gracenote was founded in 1995 as CDDB by a pair of software
   developers and music fans as a fun and easy way to identify and
   categorize their CD's. As word of the innovative and useful service
   spread, it grew to be a "must-have" application for internet-enabled
   music players. From a user base of 2,700 in 1997, today Gracenote
   serves nearly 1 million users each day.

           CDDB Perl Module [doc] 
       CDDB is a high-level interface to databases based on the Compact Disc
 Database protocol.
 Starting in version 1.04, CDDB.pm will contact freedb.org servers by
 default.  This change is in response to Gracenote's CDDB denying
 CDDB.pm connections and failing to answer my e-mail.

       Database entries must be in the ISO-8859-1 character set (the 8-bit ASCII
 extension also known as "Latin alphabet #1" or ISO-Latin-1). Lines must
 always be terminated by a newline/linefeed (ctrl-J, or 0Ah) character
 or a carriage return character (ctrl-M, or 0Dh) followed by a newline/linefeed
 character.
