Does someone know if CDDB does similar things?

The Compact Disc Database (CDDB) protocol is used to query the database at
cddb.com (http://www.gracenote.com) for information on audio tracks, but it
is software independent and several different players and libraries make use
of CDDB.

A query includes the following components related to privacy

    libname       # Name of the player or library   
    libver        # Version of the player or library
    cddbmail      # cddb-test () submit cddb com

See the perl package CDDB-1.08 for more information at

In my opinion the above information are not sufficient to generate profiles
about individuals, although they allow the generation of general statistics.
But this is rather normal for a database service. ;)
