if they were ogg files (or others that support arbitrary metadata tags) 
we could optionally embed the metadata as arbitrary tags in the file 
itself. This is something that would be settable in a future version of 
Tracker.

I have been looking for a lib to handle this but TagLib is not suitable 
 (as far as I could see in the C interface for Taglib) so I might 
optionally link with gstreamer for tag reading/writing (which has the 
advantage of ripping the code straight from rhythmbox) or just use 
libvorbis directly for this.

The embedded metadata tag names would follow the spec at

http://freedesktop.org/wiki/Standards/shared-filemetadata-spec

and only *writable* metadata as defined in that spec would be stored so 
music players (assuming they are not using tracker) should still be able 
to read in this info if its there. (metadata that is already embedded 
like artist would obviously not be duped here but writable stuff like 
"File.Keywords", "Audio.LastPlay", "Audio.PlayCount", "Audio.MBAlbumID", 
"Audio.Lyrics" etc would be present)
