I think there is definitely a need to replace some sound files in games
maintained by the Debian Games Team because of license restrictions thus
your initiative is most welcome.
I was thinking about creating a "games-music" package myself that
includes a couple of free music files of different genres. This is
mainly because I have to replace the whole soundtrack of M.A.R.S, a game
I intend to package but I think other packages like foobillardplus could
also recommend or depend on it.
@all: Please let me know if there is any interest within the Games Team
to create such a general free music package, then I would propose some
tracks from Jamendo and take Hans de Goede's list into account.  Of
course we can still update the package with new and different songs later.
