The dynamic duo of CDDB.py and DiscID.py, along with their side-kick C module cdrommodule.so, provide an easy way for Python programs to fetch information on audio CDs from CDDB (http://www.cddb.com/) -- a very large online database of track listings and other information on audio CDs. Note that for CDDB.py version 1.3 and later, the default CDDB servers have changed to FreeDB, as GraceNote, the owners of the previously-free CDDB archives, have become unreasonably restrictive with access to their database. See http://www.freedb.org/ for more information on FreeDB.
