Re: Common music database?

Ok i just saw the shared metadata spec for the first time, and i'd propose
to include HAL volume and device UDI to that (yes, i know that HAL is
currently basically only implemented on Linux, but never the less), and
another thing that i'm not sure about, "Audio" is a subclass of "File",
which means that it's basically already what i've proposed?
