With the increasing amount of audio and media other than text and images
being uploaded I think it could be worth considering the creation of an MfD
(Media for Deletion), to undergo the deletion of other media in a similiar
way to RfD, CfD and IfD. It could be useful for handling sound which may be
copyrighted, and for other media uploaded inappropriately which lacks an
obvious place to be noted.
If other forms of media than audio are unlikely to appear in the near future
it may be a good idea to instead create AfD (Audio for Deletion).
The volume of audio appearing could rapidly increase with the introduction
of WikiProject Spoken Wikipedia, meaning that the best time to create such a
system is now.
