.flac - application/flac
Why not audio/flac?
Presumedly to distinguish it from "unencapsulated" flac. I'm not sure this makes sense though. Native flac is a fairly light container, and I suspect the current application/x-flac usage is just an analogy with ogg. OTOH, I don't think anyone's done flac over rtp, where this would be needed, but that is something that's interesting.
