Also, there appears to be some sort of software which, when people use it to play WAV files off my page, automatically looks for a matching file with 7 different extensions. And then adds /subtitles to the path and tries again with all seven extensions.
I'm sorry, that's just annoying - I don't want some dumb software splurking 14 hits into my 404 log just because someone's using it to play a WAV.
*sigh*
